I have the similar issue, but I got this error from appcenter builds. Settings the ENABLE_BITCODE=no will successfully run the build but this is NOT a good workaround. I'm still investigating this issue and what lib/pod is triggering this error. btw, did you managed to find a fix?

I found out what was causing this issue: a library that was updated 5-6 days ago, compiled with Xcode 12.5 for M1 chip support the library used is RealmJS - https://github.com/realm/realm-js My suggestion is to find out which library was updated and try to downgrade it to a lower version.
