Description:
You can select a variation, but then LibreOffice's preview window closes, then it freezes and becomes completely unusable, forcing you to close the program, reopen to where you were, and if you hadn't the prescience to save your file immediately before the bug happened, you basically lose what could be a lot of work.

My device is an LG Gram running Win11. But it could be happening on other platforms/systems as well; in fact, is probably happening.

Steps to Reproduce:
1. Open the Slide Transitions Panel in the sidebar.
2. Choose an animation (e.g. Wipe).
3. Attempt to select a variation (e.g. Left to Right).
4. The software hangs.


Actual Results:
There is a flickering, persistent loading or working icon in the bottom corner.

Expected Results:
Ran Wipe > Left to Right in a preview.


Reproducible: Always


User Profile Reset: Yes
