@KGIII, I think it sounds like a 'marbles' thing
The OP has been avoiding giving us the info we need to do our work here, since Jan 3, 2023
He fails to realise that without that input from him, it becomes extremely difficult....bordering on impossible...to answer and solve his problems.
For example he may still be running a very early version of Linux....like 18.3 or 17.1....which of course no longer receive the necessary updates to keep them either secure or up to date.....So the operating system is out of date and so will the apps in it...be also out of date.....This includes Libre Office....quite possibly out of date and running in an out of date OS....makes the situation beyond help.
I do realise that it is hard for him to alter his habits, and that he is wary of disclosing information, but in this case the person being hurt is him.
It would be my guess that a new install is absolutely necessary, but is beyond his current ability to do that.
He actually needs one on one help. If we knew where he lived, a member from a Linux User Group would be ideal for him
