For me it was related to static vs dynamic builds, detailed it here: https://stackoverflow.com/questions/72291080/itms-90334-invalid-code-signature-identifier-when-building-via-xcode-cloud/73653319#73653319

Any resolution on this? I also get the reload to authed AppStore landing page in one of my projects. In another one of my projects it resolved itself after about a week

Can confirm this worked eventually- might also help to delete your Xcode Cloud data on AppStore and set it up again
