VRCSDK3 errors (858035)

Hello,
I’m trying to import some Avatars into Vrchat, but I get these 3 errors:


And I simply cannot it because the Vrchat SDK window doesn’t appear in unity, someone knows how to fix it?

Looks like something that the sdk expect to be there is missing.
Make sure you use the correct version for the SDK version you use.
The current version for the newest SDK is at this date Unity 2019.4.31f1.
