Looks like whatever zip file you got is a vrchat cache rip run through utinyripper, which is going to be harder to reimport and have lots of weird errors like the script issues.

If this is really your first time ever uploading a model, you should really start with a premade one from vrcmods, one of the booth models, or an mmd import. Learn the ropes there, then come back to your ripped model.
