We have updated to a new docker jenkins version Jenkins 2.387.2 and after that, we can't access any jobs from a web gui nor the runs of the jobs, configuration etc. Jobs seems to be running but with lots of exceptions - hard to tell. Jenkins is unusable in this state, sample log contains this - see attachment. The exc.txt is an exception from job running there, after we manage to kill it the parts of the jenkins we already usable, but when we started another it was back to no good again.

After some more tinkering, we manage to get it running with old plugins from the backup so it might be some plugin
