I have similar issue as ichaleynbin in the previous thread. I tried to claim one of my old plugins and one with no maintainer to improve. After claim I got some red error without any info.

my old plugin to fix an issue

https://umod.org/plugins/tell-my-vote
unmaintained to add new features

Users with no plugins are not able to submit claims, it would have to be done manually.

I still have one plugin active
