I am trying to run a project that uses Expo, but I am running into this error

$ expo start --ios

I’m on a MacBook Air (M1, 2020), macOS 12.0.1, Xcode 13.1, and I have this

$ xcrun --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
$ xcrun --show-sdk-version
12.0
$

I have tried re-installing Xcode, reinstalling the command line tools, running xcrun simctl erase all but none of that helped. Googling the error produces no results. When I do xcrun simctl list the ID in the error, 84732E63-ABA0-4C7F-8AC8-AA89BB69AAD3 isn’t in the output.

I’m able to do expo start, but once I hit i, it crashes with the above error.

I had to open the Xcode simulator manually by opening Xcode then going

Xcode > Open Developer Tool > Simulator

after doing that once, expo start --ios works and opens the simulator on its own.
