My version of Xcode was recently updated to 13.3. Now, I can not launch any simulator. I get an "Unable to Boot the Simulator" error from any iOS 15.4 device. I have deleted all 15.4 devices, and am downloading 15.2 devices to test. Some other sources are reporting this, too, but I saw nothing on the Developer Forums so thought I'd open a question here. Hoping for speedy resolution so I don't have to use Android emulators :(. (I develop on Flutter, which is cross platform)
