Unity2D not wanting to build at all, no matter what I do...

Hi, I’m having trouble building my project, everytime I try to build (by the “Build and Run” option) I get granted with 41 errors, no matter what I do! I tried changing versions, moving files out of the project, building with only one scene, even reinstalling Unity! It has been 4 days since I’m searching for a fix, and I cannot find any…

I would appreciate any help given.

Note: I’m on 2021.1.2f1, tried with 2021.1.1f1 and I wanted to build for Windows

I have something to add to it

When I build from the build settings, it succesfully builds, but I cannot launch it, it crashes before the “made with Unity” can appear.
