I encountered the same issue after upgrading from 2022.3.8f1 to 2022.3.12f1 the project was working fine before upgrading. I tried to clear the cache but it was not working.

Here are the errors appeared:

This errors messages indicate that the client and server have different versions of the "Character" ghost, leading to a hash mismatch. I do not know why this happened.

Hearing from you soon.

Thanks in advance.

 

Wow, It works. Thank you.
