v14.2 is not viewed administrator page. how to fix?

It was my fault that the administrator screen did not show up. Removing the plugins that I had added independently solved the problem.

works good with14.3.0
postgresql 13

Did it work on bare metal with Ver.14.5?
In my environment, no.
I don't know why.
