I've been trying to upload a test build using Xcode 13 to TestFlight but keep getting the following error after build is uploaded successfully: ITMS-90755: Invalid Binary - The following binaries in your app contains prohibited instructions: /Volumes/data01/app_data/awf/SWImportWorker-pv50p00ce-swpr152.cse.apple.com-400203/ff08-SoftwareImportWorker-PV_.0/VWBGHTOVAUPPUUZ65REE64UUN4/eqbyjijjamvooymq/exddmvmbsqjsrxwj/Payload/[App Name].app/[App Name]. Remove the instructions from the binaries, rebuild and resubmit. What does this error mean? What are those prohibited instructions? Where to fine them in the app binary? Any guidance is appreciated. Thanks.
