How to fix unity package manager errors?

Question

I use unity 2022.1.21f1. I wanted to add the urp package to my project with package manager but in the console there was a lot of errors. I also tried to add other packages but situation is the same. Errors said "script has no meta file, but it's in an immutable folder. The asset will be ignored". How can I fix this?

I tried to delete plugin's folders from MyProject/Library/PackageCache. I tried to reinstall package.

How I understood 2022.1.21f1 is not stable. The solution is quite simple. I just updated unity to 2021.3.16f1.
