There is another open thread on this topic. NLTeo's answer in that thread solved the issue for me. The solution was to switch from app specific login to Apple Connect API Keys for authentication. I've copied NLTeo's post below for convenience, since I can't cross link
Create API key and download it https://appstoreconnect.apple.com/access/api
Copy key-id and issuer from same page
Store to keychain
xcrun notarytool store-credentials Notarize --key apple-connect-api-key.p8 --key-id 1234567 --issuer 11f28c89-0bbc-47b8-bb65-ad719eb08e4c
Use to notarize
xcrun notarytool submit ParetoUpdater.zip --team-id 12345678 --progress --wait --keychain-profile "Notarize"
