I'm facing the same issue.
I was using Xcode 12 before and it was working fine. The problem started to appear when I updated my Xcode and installed simulator for iPhone 12.
I have tried reinstalling Xcode 12.0 from developer portal along with developer tools for Xcode 12.0. No luck yet.
Should I go back to Xcode 11.7? Would it help?
