Mac OS Monterey 12.6. libre office 7.3.6.2. given full access to Disk, Skia inactivated, Have reset Nvram.
Libre crashes within a few clicks every time, especially on copy and paste. Appears to work on my guest account. Can I alter my account parameters in any way?
Try to restart in safe mode by resetting your user profile. But before, just in case, backup your user profile (not on MacOS, I don’t know its location there).
Add-on to @ajlittoz’s comment: See LibreOffice user profile - The Document Foundation Wiki for help. Note: you rename the old profile, so your user settings are safe, and you can later copy them from the old profile to the new one. Do that when LibreOffice is not running.
Are you using any accessibility functionality, such as a window manager, e. g. Rectangle, BetterTool, or VoiceOver, screen magnifier? These are known to cause crashing with LO in some circumstances, especially when switching contexts.
