Testflight doesnt open an App (error 10673)

I've successfully uploaded my macos app to tesflight (it's a game based on Unreal Engine5). It has passed all checks and is now in testflight, but when i launch it it says "The application <App Name> can't be opened. -10673" And pops up another windown : "The beta app, <App Name>, is no longer available. The provisioning profile is invalid" The provisioning profile doesn't specify OS versions - it's signed with distribution and installation certificates for AppStore. What would cause this? How can I fix this? MacOS version 14.5
