Unfortunately my LibreOffice install hasn't been working right.
My old LibreOffice wouldn't crash, as long as I didn't do anything
fancy (Ctrl+X or Zotero-Insert Citation).
But I wanted to upgrade in order to stop it from crashing at all.
So I uninstalled my old version, removed reg conflicts
Hello,
Good thing to have thought about ccleaner to clean the Windows registry but
you should retry to uninstall but this time by deleting your LO profile.
Then try first with Hebrew, Chinese and Japanese and any extension/custom
just to see if it's ok. If it's ok, try to add 1 by 1 your customs
