Enjoying the same error.
Trying to launch Unity, I get the above diagnostic registering Project Manager’s health check failure. Trying to pen it results in, “The procedure entry point Event SetInformation could not be located in the dynamic link library Advapi32.dll.”
So Windows 7 users can’t launch Unity 2021 LTS. None of the solutions listed fix the issue. 2019 and 2020 run fine with no errors.
[EDIT!]
Fixed, with the stupidest primate brain solution possible: I deleted the Package Manager folder from the Resources folder. Copied the Package Manager folder from 2021.1.22, to the 2022.3.0f1 Resources folder…
…walla. Runs fine. Throws warnings but they are fixable.
