Failed to load package manager -- PLEASE HELP!! (in desperate need)

Hi, these errors suddenly appeared while I was working on a school project. Unity was working perfectly fine for me this morning until a couple hours ago. All I did was moved my project folder to the repo folder I cloned for my school project and now suddenly this is occurring for me across ALL projects (even when I try to create a new project).

I am running on Windows 10. The following are a sample of the errors I am getting, as I do not know how to get to the console error log. There are 187 errors and 4 warnings so bear with me please.

Failed to load package manager

PLEASE HELP!!!!! I CANNOT FIND THIS ERROR ANYWHERE ELSE ONLINE!!
It seems to have only occurred on one other thread but no solution was provided on that thread.

I did not make any changes to my network settings.
I did not change anything on my computer except from the time when I pushed my changes to my project repo on GitHub.

Unity was working perfectly fine this morning.
I have already uninstalled and reinstalled multiple times.
I am using the most up to date version of Unity so there is nothing I could upgrade to.

PLEASE HELP!!!
