The issue you are facing:
I have a Debian 12 latop with KDE Plasma (X11) and I installed Nextcloud-Desktop 3.7.3-1 from the Debian 12 repo. The client uses 99%+ of my CPU at all times. It is completely unresponsive and the only way I can close it is to kill the pid from terminal.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Boot up laptop and login.
- It works fine on my other laptop running Debian 11
