If you haven't upgraded to 22.3.0 yet maybe hold off.
I am finding that 22.3.0 is crashing every time I open a sequence UNLESS I first open the sequence in Source Monitor before double-clicking to open in a timeline.
I am on a 2020 fully maxxed out iMac intel processor 16GB Radeon GPU 128GB Ram
This problem did not happen in the 22.2.1 version I upgraded from.
There are other crashes happening as well but this Sequence opening crash is the main problem. It also crashes if I double-click a clip that is itself a sequence and I have not yet opened that sequence in Source Monitor first.
As long as I open all my sequences in Source Monitor first before opening them any other way its fine.
BTW Its a very abrupt crash. The application just closes with no opportunity to save and it does not save itself either so I am constantly losing work even though I set my auto-save frequency to only 1 minute 😞
Trying to remember to manually save before every step is difficult!
22.3.1 is having the same crashes PLUS the UNDO Queue frequently does not work. I'll do things and they will not be recorded in the History steps so pressing Undo causes very weird problems or undoes an action many many steps ago. Thats terrible.
