I installed version 4 on Max 2024 and I can’t open it.

I can’t uninstall version 4 and revert to version 3. Any solutions?

Hi!
Your database is certainly fine. That error wasn’t
a data problem: the plugin just tried to open the database while it was
still being updated in the background, and timed out. Nothing was damaged.
I’ve prepared a new build that handles this situation gracefully
(it now shows a clear message and closes instead of erroring). I’d recommend
installing it — https://3d-kstudio.com/my-account/downloads/

After installing, just reopen Project Manager.

If the error comes back even after that, send me the log file so I can check
exactly what happened (no rush, your data is safe and backed up):
%LOCALAPPDATA%\Kstudio\data\logs\kstudio.log
