NO iOS 14 6 Simulator Found Anywhere

Question

I developed an app for a client in React Native. I fixed it for all the versions Apple said it didn't work on, except 14.6.

Apple is saying the app doesn't work on 14.6. However, I can't find the 14.6 Simulator anywhere!

I've also tried downloading Xcode 13 beta, but the Simulator versions skip 14.6 (it goes 14.5 and then 15.0). I've also tried it on the latest 12.5 version (12.5.1). Here's an image:

Please help.
