Fusion Crashes after removing keyframes

Hello,

I am having issues with Fusion crashing after removal of the keyframe (both Standalone & in DR). For example using transform node I created 2 keyframes. When I remove my last/first keyframe in either Keyframes or Spline tabs Fusion will crash each time on such operation. I don't recall having such problems previously. Is this known issue in the latest release. (I am on the Fusion Studio 17.4.1).

Thank You for any update on this.
Peter.

Same for me since 17.4 on windows. I’ll have ti check on Mac tomorrow. Workaround is to untick the orange losange in the inspector tab but very uncomfortable.

Thanks Greg, thanks for the workaround! Hope this will be fixed in the upcoming release as it makes now hard to work with lot of keyframes in fusion

Yes I agree this is very annoying!!!

I couldn't recreate a crash deleting keyframes in the Spline Editor, but I did manage to repeatedly crash Fusion Studio 17.4.1 by deleting any keyframe in the Keyframes pane.

It doesn't actually crash immediately. After deleting the keyframe, it keeps running until I next click a mouse button, then it does instantly. This is regardless of where I actually click.

Here's a crash log from macOS when deleting the second of two keyframes on Transform -> Size, using the Keyframes pane

I have the same thing happening with an opacity keyframe. The only thing I can see when looking at the node in a text editor, is that the keyframes are not on "whole" frames. I'm including the node that is crashing for me in hopes this helps track down what's causing it.

I still can't recreate a crash when deleting keyframes in the Spline Editor - including in dual screen mode in both Fusion Studio and Resolve Studio, and including with the node that Ryan posted.

Only the Keyframes pane crashes for me.

Is it crashing all the time for you guys when you delete in the Spline Editor?

It's a 17.4.1 issue. Should be fixed in the next release. For now, either live with it, or revert to 17.4.

Thanks for the confirmation Dwaine. It is always nice to have a feedback even when it is a bad news.
I'm not 100% sure but I think I got that issue with 17.4 too.
How urgent is it considered ?
In other words when is the next release scheduled?
Regards.

[Dwaine Maggart]

My testing didn't show it happening on 17.4.

I can't comment on when releases will happen.

For now, either live with it, or revert to 17.4.

For this alone it would be great if the Fusion Studio installer could offer a custom install path.
