During app submission process, Apple assumes that upload-symbols.sh script is a file that needs to be signed.
Remove the upload-symbols.sh script file manually from the Shake.framework directory before Archiving your app.
Issue is present in the 14.2.0 release and will be resolved in the future releases.
AppStoreConnect submission is failing with the "ERROR ITMS-90035 Invalid Signature"
Manually delete the upload-symbols.sh file located in the Shake.framework/ directory before archiving.
