I can't open file in LO 7.0.1.2

I just installed newest version of LO
In addition my IOS is updated to MacOS Catalina 10.15.7
In the preferences the path to my documents should be changed, but I was unable to edit this line.
Perhaps this is the solution to my problem?

Please give me advice.

Thanks in advance.

You probably need to give LibreOffice full disk access from System Preferences > Security & Privacy. See this site on how to do it if you aren’t sure: Explained: What is Full Disk Access & Full Permissions on macOS Mojave .

Once you have done this then you could change the path. Cheers, Al

Thanks.
Problem solved.
