After Build the list of Jobs dissapear

Hi,
I have to find a solution to a problem at our company. We use Jenkins 2.452.2
My Problem is that after a Build the Jobs dissapear from the groups so in the Named groups have no Jobs in them, and just at the “All” can I see the jobs.


It seems that some of the plugins make a clean up or something altough I cound not find any evidence to it.
Could you help me to find the solution or point me to a ticket where this is solved?

I habe restarted Jenkins and noticed that it removes the jobs from the Groups visible at the above image.
This was the log of the restart. Maybe just a little restart configuration could fix the issue:
Anyone had something like this before?

I’m not aware of that problems.
Does it mean you can reproduce the problem by restarting Jenkins without any jobs running? If yes do you have by chance some init.groovy script that creates those views on startup and then overwrites the configuration?

Yes, I can reproduca by new start. I do it from the Tools and Actions (on the website of Jenkins with the “Restart Safely” ones no jobs are running. I do not have access to the groovy file but I try to look inside today.
Maybe there is a problem with my plugins. Here is a list of the deprecations.
Do you think this can cause the problem and if yes how can I solve this?

I recommend to uninstall the plugins, thought they should not be the cause of the jobs disappearing.

Thank you for your fast reply. I highly appriciate your advice and we are going to do exactly this. Thank you!
