Help is appreciated
There may be deprecated plugins installed on your system that need to be removed.
The Jenkins project stopped distributing the Ruby runtime plugin, the Python runtime plugin, and plugins that depend on those two plugins in January 2022. You can find a detailed list of plugins and more information in the blog post:
That ID is written to the Jenkins log file with a stack trace. Read the Jenkins log to see if it guides you on your next step.
I assume that disabling the deprecated plugins is enough, but ultimately you’ll want to remove them completely. They are no longer usable.
The ruby runtime plugin does not support Java 11 at all. Jenkins weekly already requires Java 11 as its minimum Java version. Jenkins LTS 2.361.1 in September 2022 will require Java 11 as its minimum Java version.
