ITMS-90053 Mac Catalyst Invalid Binary

I am really stuck. I uploaded my Mac Catalyst app. The binary passes validation beforehand. I submit for review. After being in "waiting for review" for a couple of minutes it is rejected with "invalid binary" and comes back with an email saying

"ITMS-90053: This bundle is invalid - The bundle identifier is already in use by a different software package."

The only app that is using the same bundle is the IOS version where I added the Mac platform.
