Help: I can't open any .ods file anymore

Whenever I try to open one of my .ods files, a .~lock file is created and libreoffice calc crashes. I tried safe mode with factory reset the user profile without success. Complete reinstall did not help either. Tried to manually delete the lock files but on every startup it is recreated.

I am able to open all of these files using excel, but i want to open them with libreoffice calc!

What more can I do? Thanks in advance…

LibreOffice version? Operating system? Some odd permissions in the directory where the .~lock.* file is created? i.e. file can be created but not written to?

I’m using win10 and the libreoffice version is (x64)

I will take a look at the permissions and report back.

All files have read and write permission for the owner and group, files belong to my user. Tried copying them onto my linux machine, where they open normally.

Can you create a new file, save it elsewhere, and reopen it ?
