Discover crashes every time on update check

Mon Jan 03, 2022 5:57 pm
Hello,
Plasma-Discover has been crashing for few weeks for me now and I can't seem to find a fix for it. I have updated the system through pkcon and through Muon but that didn't help. I have also tried to delete plasma-discover and install it again but that wasn't helpful either.
I wonder if anyone here may be able to help me? Terminal output is below. Thanks in advance for any insights.

Code: Select all
$ plasma-discover

I have the same problem. I'm not able to update my machine since weeks now :'(
Manual pkcon refresh && pkcon update also did not work.

Am grateful for any help.
