I don't know anything about Libre Office.

But since you have both MS Office and Libre installed, problems can of course arise with Libre, as the files also have a different ending.

My humble opinion is to uninstall Libre and fix Office through Control Panel afterwards.

Possibly also carry out an update in your pc.

Of course, the problem could also come from the pc itself.

The variable many, from activating Bitlocker to encrypting individual folders.

As already said, carry out the above options.

If this does not solve the problem, I recommend that you contact a service technician who you trust.

Thank you for your understanding and patience
