Could you share any additional information about the build setup/any way to reproduce the issue? This looks like a deserialization issue, which often is fixed by cleaning (deletes serialized modules) + rebuilding. As a more drastic step, deleting the DerivedData folder for the project is also an option.

Comment by Eduardo Dias (JIRA)

I think this one was not related to the derived data as I removed the entire dir before each build. I suspect this issue was related to the new ARM64 architecture set on my project dependencies and running on simulators. I managed to solve this issue removing this architecture explicitly on my project settings.

I'm also not able to reproduce it anymore, so I think we can close this one for now
