Audio Transition Shortcut Not Working and breaks UI

[Amal MP]

Issue:

Adobe Premiere Pro fails to apply audio transitions using the keyboard shortcut Ctrl+Shift+D. Adding transitions via handles also doesn't work. Attempting to adjust volume with keyframes breaks the UI, hiding the mouse pointer. Also attaching a screen recording for your reference.
- Steps to Reproduce:
1. Open Adobe Premiere Pro and create a new project.
2. Add two clips to the timeline (make sure you have enogugh frames for the transiton to apply).
3. Try applying an audio transition using Ctrl+Shift+D.
4. Attempt to add a transition using the transition handles.
5. Add two keyframes on the first clip and try lowering the volume with the second keyframe.

Expected Result: Audio transitions should apply correctly, and UI should remain functional.
Actual Result: Transitions don't apply, and UI breaks when adjusting volume with keyframes.

- Tests done:

1. Reset App Preferences

2. Cleared media cache files

3. Reset plugin loading cache

NB: There is no porblem for adding and controlling audios with keyframes unless first fails with the default audio transition shortcut.

Hi @Amal MP - 
Sorry you’re dealing with this we know how disruptive these kinds of issues can be.
Do you remember if this started in the latest version, or has it happened before?
Can you send the project and media to jamiec@adobe.com so that we can investigate?

Hi @jamieclarke , thanks for the reply. I think this issue started with Premiere Pro version 25.2.0 (build 147). I'll send you the project file and media later.
