XCode 12.5 abort trap 6 on building(after downgrading)

I had a project that was created on XCode 12. Next I opened it in XCode 13 beta 5 and made lot of edits. Now it does not build at all in XCode 12.5. I tried clean build but still doesn't work.

 Command CompileSwift failed with a nonzero exit code
1.	Apple Swift version 5.4 (swiftlang-1205.0.26.9 clang-1205.0.19.55)

2.	Running pass 'Module Verifier' on function '@"xxxxxxxxxxxxxxxxH0OSo014AVAsynchronousA18CompositionRequestCtF"'
