Dragging playheag backwards locks Davinci Resolve

Having a recent issue after upgrading from 18.6.6, to the Studio fully paid version and then to the Beta19. I am finding that if i have a time line playing and grab the playhead to move it back to replay a section, it locks the program. It may momentarily freeze, but also may lock the program and become unresponsive. only way out at that stage is to kill it in Task manager as it wont close or respond in the Window.
I do have a NZXT system monitor which shows the GPU usage drop to zero and minimal CPU usage. This would indicate Resolve is not utilizing extreme system resources to do anything at that point. Its just not responding apparently due to a conflict or error. The system worked fine before going to the Studio Version, even running timeline editing in 4k. Hope you can point me in the right direction. Thank you in advance.

Please indicate Resolve version, operating system, and include a system spec.

Is this behaviour on the Edit or Fairlight Timeline?

What is the source media format and codec?

What are the Timeline Settings (e.g. resolution and frame rate)?

Can you include a video illustrating the behaviour?

Well, it's a beta and problems are to be expected. You should report in the beta subforum. Jim Simon has reported a similar issue under windows, which I can't reproduce here on a Mac.
Use 18 for production work.

Yes fully understand. I moved from the free 18.6.6 to a fully paid Studio subscription. I noticed the issue shortly afterwards. At this point I checked my BIOS to ensure all settings GPU and CPU were working unhindered on the best settings. Still had the problem.
At this point boosted RAM from 16gb to 32gb becoz i could aand was a cheap upgrade. No joy. I then installed the Beta19 in case it was an issue fixed in the newer version. Alas same issue still present.
Looked at upgrading the hardware (ie, build new box) but will hold off for the moment. I have ordered the GPU (Intel Arc A750 8GB PCIE-4) as a temp upgrade that would still be useable if i build something new.

Just an update having read some similar behaviour topics on Google.
This is true for my issue. In hindsight this did happen at similar time as I discovered the
new "Dialog Leveler" or "Voice Isolation" tabs in the inspector menu 0n edit page. These are enabled on the clips in question. Also when dragging the playhead backwards i am getting a buzzing sound rather than voice in reverse.
Does this post possibly belong in another Forum section relating to Audio or AI ?

There is this forum for the public beta: viewforum.php?f=38
I'm sure developers will follow that forum more than anything else.
