Same here. Mine gets fixed when running sudo xcrun simctl shutdown all from within the vm, running this sudo-less doesn't work. Did you find any solution/workaround?

I'm still fighting the same issue... I tried Xcode to 12.1 GM, Xcode 12.2 beta 2 and latest stable with no luck.

sudo xcrun simctl shutdown all temporary works for me, after some time of inactivity (no CI jobs on vm) the errors pops right back and I need to manually run the same code again. Has anybody found a concrete solution?

I'm experiencing this same issue on my M1 MacBook Pro running Big Sur 11.0.1.

Two years later and still the same issue!
