I am experiencing this with Xcode 12.0.1. The workaround with xattr -rc does not work for me.
I can confirm I downloaded and unzipped this project from the internet (gitlab). The crash is immediate upon opening that version.

@mkII no voila for me :/
Final word from Apple after filing a Technical Level support request for the missing iOS 13.3 Device Support files - this courtesy is officially discontinued:>Thank you for contacting Apple Developer Technical Support (DTS). >The behavior and resulting limitations you describe are by design. Moving Device Support files between Xcode versions is not supported.
We have a React Native app that has Swift 3, C++ and Objective C code, and the import handling changes in Xcode 11 + React Native version we are currently stuck on will not allow us to use Xcode 11 without considerable refactoring. We still need to test & ship apps on iOS 13.3 iPads, as we have a hardware specific app. So we've been using old Xcode with new Device Support for the iOS versions. But it looks like this may have forced our hand in refactoring!
Hi Claude, I'm not experiencing that. I need the 13.3 device support files because I must use an old version of Xcode for my project, and I import the Device Support for every new iOS release so I can build for it. I opened up the new Xcode and the device support files are not there. Taking your advice (that 13.2 covers 13.3) I just moved the 13.2 device support to the old version of Xcode and I get the same "Could not locate device support files" error. The 13.2 device support files do not cover 13.3 based on this test. What is Apple doing here? Honestly I am trying to figure it out maybe I'm missing something - why would they hide the device support files in a new part of the Xcode file structure for 13.3? I can confirm I can build to 13.3 from the new Xcode, but that means the device support files are somewhere in this new Xcode application file. They must be in another place!Called Apple developer support about this (twice) and the phone rep couldn't comprehend the problem or find these forum entries.The search for these device support files continues, as I can't build our app now. 😟
