Yes, I'm hoping someone will have an idea. I can provide more diagnostic logs if it would help. As far as I can tell, I've followed all the procedures to sign and notarize the app as specified, and my terminal commands confirm that it is properly done.

The Malware warning is a popup reading: "Form" Not Opened Apple could not verify "Form" is free of malware that may harm your Mac or compromise your Privacy Done One has to go into the "Privacy & security" settings to then allow the app to run and then verify it in a second popup with the user password or biometrics. The app runs fine. There are no bugs.
