Description Cheddar Fox 2025-02-05 23:06:35 UTC 
SUMMARY
It used to be that if I held Alt I could select just one clip in a group to delete just that part of a group. Now when I do this it deletes the whole group even though it still visually selects just the one clip.  On top of that now if I selected multiple clips in the group at the same time to delete multiple clips from the group the application crashes. Auto recover also fails as it tries to recover the bugged save state.

Lost most of my work this afternoon.

Thank you for reporting. I can confirm the crash. Following your steps. 

I tested it with 3 different color clips: with Alt + Shift I selected 2 of 3 clips in the timeline -> hit delete -> crash
