Switched to Studio now unable to scrub timeline in reverse

I just switched over from the free to the studio version of resolve and now I've been having issues I've never had before.
Normally when I'm scrubbing over my timeline in Fairlight or Edit I use a wheel or my arrow keys.
Since moving over to Studio my backward arrow and wheel movement don't work.
I checked the keyboard settings and those are still the same.
If I use my mouse or pen I can move the timeline in both directions.
This and the constant spontaneous closing of Resolve is making me regret buying Studio and I might ask for a refund...

Can someone please help me to fix this issue?
Thank you all.

UPDATE: Found the issue, turning OFF audio scrubbing did the job

Which hardware (CPU, GPU, RAM, disk I/O)? What specific version of Resolve? What OS? What source file codec? What timeline settings (res and fps)? What framerate? How does your drive rate with Blackmagic Speed Test? How is the drive formatted and connected? Which GPU drivers are installed? What are your cache settings?

I can tell you that Resolve 19.1 is working on all our systems "so far," and I haven't seen any jog/shuttle problems at all. This is on an M1 Mac Studio Ultra and also an MacBook Pro M1 Max, each running Sonoma 14.7.1.

@Marc Wielage You are asking a noob a lot of technical things I have no clue about. I just know it worked fine with the free version 19.1 but now with the studio 19 version I'm having issues.

I don't think that is default setting. Maybe you changed it at some point. Try resting the keyboard shortcuts by reverting to default preset.

Audio Scrubbing can be turn on or off in the Timeline menu.

In the program prefernces, User - UI Settings: 2D timeline scrolling: Checking this box will scroll the Timeline vertically through all the Video or Audio tracks when moving the mouse wheel. Unchecking this box will scroll the entire Timeline horizontally when moving the mouse wheel.

Fixed or Free Playhead? You can choose whether to keep the default fixed playhead on the Cut timeline (video flows under the playhead), or have it move freely with the video instead (playhead flows over the video). To choose the mode, click on the Timeline Options icon, and check or uncheck Fixed Playhead.

Scroll Wheel Controls on Timeline

Additional scroll wheel and key presses can be used to manipulate the Timeline on the Edit page.
To manipulate the Timeline, rotate the scroll wheel while holding down:

— Shift: Expands or contracts all the Video or Audio track heights, depending on what section the pointer is located at when you scroll.
— Option: Zooms in and out the view of the Timeline.
— Command: Navigates forward and backward in the Timeline.

Scrolling Through the Timeline

When you’re zoomed into the Timeline, there are several methods you can use to scroll around
as you work.

— You can scroll left and right, or up and down, by dragging the Timeline’s horizontal and vertical scroll bars.
— You can scroll left and right through the Timeline, one “page” at a time at the current zoom level, by selecting Playback > Next/Previous > Timeline Page. If you use these often, you can assign them a keyboard shortcut.
— You can also scroll up and down the tracks of the Timeline using the scroll wheel, scroll ball, or scroll gestures of your mouse, trackball, trackpad, or other pointing device.
— You can also scroll within the Timeline by middle-clicking and dragging in any direction, which works the same as panning around a viewer that you’ve zoomed into. This frees you from having to use the scroll bars as you move around your edited clips.
If you scroll past the position of the playhead, a small playhead indicator appears in the bottom scroll bar to let you know where it is relative to the entire duration of your edited sequence.

What is the exact name of the command in the keyboard shortcuts window and what key do you have it set?

You really should know these things before you try doing this work.

It's been my hobby for about three years unfortunately I just have no affinity with the specs of my Lenovo gaming laptop I use to edit as it has worked perfectly till now.

I set them to the arrow keys.
And I set the dail on my keypad to be the arrow keys.
But both the normal arrow keys and the dail will scrub forward but keep getting stuck on going backwards.
I'm having a hard time explaining in English what I mean.
It's also only on the Fairlight page.
That's also the page Resolve stops working on when it fails, every time only while using the Fairlight page.

I suggest you reset the keyboard shortcuts, its unclear if there are conflicts or not. Also make sure there are no other applications using shortcuts on system level and conflicting. Since you have a hard time explaining what is happening, you are going to have to figure out it on your own or provide more relevant information.

It's just strange to me that everything has been working fine till I switched over to the Studio version.
I did not change any setting myself, I checked and they are still all the same as before.
I went to being able to scrub forward and backwards on the fairlight page in the morning in the Free version.
To having the whole application freeze several times while working in the fairlight page and not being able to move backwards on the timeline while trying to cut out pieces.

So is this purely that the Studio version is pushing my laptop over it's edge? If so I might have to return to the free version.

If you use the JKL keys will the timeline play both forward and reverse?
No problem here with the arrow keys in either forward or reverse. Without knowing what your computer specs are it is hard for any of us to come up with a diagnosis. At the very least, what exact model of computer do you have?

It's a Lenovo IdeaPad Gaming 3 AMD Ryzen 7 5000 Nvidia GeForce RTX AMD Radeon graphics at least thats what's on the keyboard stickers.
But again, why does this matter?
It worked fine with the free version, nothing has been changed in the settings I just switched to the Studio version.
So it went from working fine with the free version to being horrible after upgrading to Studio on the same day.

Here's something to try which may help performance. In Windows go to Control Panel/ Programs and Features. If you have DaVinci Resolve Control Panels installed click on it to highlight it and at the top of the page click Uninstall. It may or may not make a difference.

I found it, removed and restarted everything but resolve still does not want to scrub backward the whole program just freezes.

I finally think I found the solution after rereading all your answers.
It was the audio scrubbing that makes it freeze!
So now it is turned off I can actually move backwards again with my control panel dial

No problem here, I can scrub forward and backwards to my hearts delight.
So, it's either under Windows only or a limitation of your hardware. Anybody else experiencing this?
