Upload to App Store fails with ERROR ITMS-90035: Invalid Signature

Every project build (tried 4 different ones) upload fails, different 2020 and 2021 LTS editors.
Was working fine 3 days ago.

App Store Connect Operation Error
ERROR ITMS-90035: “Invalid Signature. Code failed to satisfy specified code requirement(s). The file at path [Name.app/NAME] is not properly signed. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose “Clean All” in Xcode, delete the “build” directory in the Finder, and rebuild your release target. For more information, please consult About Code Signing

Right now I’m facing the same issue, how did you manage to solve it?

Is this using 37f1 by any chance?

I can’t seem to upload 37f1 builds to test flight, but just tried a 36f1 build and it worked first time.
