Mach-O header code

I have some problem while I try to distribute my app to the App Store: I get an error message- “Found an unexpected Mach-O header code: 0x72613c21”. Why? How to fix this?

Check out this StackOverflow thread: validation - Found an unexpected Mach-O header code: 0x72613c21 in Xcode 7 - Stack Overflow

I have seen this. But it didn’t help. The Xcode version is 12.4 (12D4e). Embedded frameworks are from cocoa pods GoogleAppMeasurement.xcframework and Pods_ProjectName.xcframework, Mach-O Type: Execution.
Have you some other links or advices?

Yes, this is a known bug in Firebase when using the Swift Package Manager:
