Problems Lightroom Classic version 10.1 on Mac OS Mojave

[#1]

Hello
For a few days now, my LRC has been systematically blocking / I can't even use the 'force quit' function anymore
The only thing I can do to unlock is restart the computer.
What can be the problem ?
Thanks for your help.

Try reverting to LrC 10.0. https://helpx.adobe.com/download-install/using/install-previous-version.html
