I figured out that you can re-download the simulators from https://developer.apple.com/download/all/. Once you download the .dmg, open terminal and change to the same directory. Then run this to install it:
xcrun simctl runtime add iOS_17_Simulator_Runtime.dmg
You'll need to do this for each simulator that's not working.
