Hey there @Renzo.mp3! Welcome to the community! If you’re login credentials are correct, the EOS invalid auth could stem from a firewall or any security that blocks or throttles networking in or out. Though another user had those issues solved (though they also had another rendering issue after they figured out the authentication). I would make a backup of your project somewhere safe, delete the Saved, DerivedDataCache, and Intermediate files, and try another build.
@Renzo.mp3 I understand how you feel, I had this issue recently and it is truly annoying but remember you will always learn something new when you encounter issues like this one. Don’t give up, ask questions and tag people of your progress in the post.
