Help, I accideltnlly broke my project by downgrading from unity 2021.2 to 2019
So, Initially I was working on my project in unity 2019.4.12f, no issues. I just hadn't upgraded, since there was no need. I then had issues with screen jittering because I had cinemachine and pixel perfect camera at the same time, and I found somewhere in another forum that that issue had been fixed in a newer unity 2021 version, to which I then upgraded to. However when I did, I found issues with low fps in the inspector play window, and my initial issue wasn't fixed, so I decided to downgrade.
After I did, I'm getting a considerable amount of errors, plus the scripts I had on gameObjects aren't loading and when I try to attach them once again, I get an error saying the script class can't be found. I also tested creating a new empty script and attaching it, and the same error shows. Any help?
