I have the very same issue, can't list all simulators, but I can list in projects created on older versions of Xcode.

This crash happens time to me on my M1 Pro running MacOS 12.1.

I have the same problem on my MBP M1 connected to a M-Audio 192/6. I have to restart the machine to make it work. Terrible experience.
