Problem solved, and it was "my fault"—rather it was caused by the Bitdefender antivirus software running on my MacBook. I had previously disabled it, to see if that was the issue, and it seemed to make no difference. But when I was poking around the Bitdefender notifications area I found the following:

Feature: Anti-Ransomeware

An app you previously chose to block attempted to access your protected files again.
App: /Applications/GraphicConverter 11.app
We blocked the app to prevent it from altering the content of your protected files

Of course I never knowingly chose to block GC. I did some more testing, and found that for some reason Bitdefender automatically blocks GC when I launch it for the first time. If I go into the Application Accesses area (of Bitdefender) it says "Blocked" in red w/ GC. But I can change it to "Allowed" and viola (Bratsche) it works.

Thorsten: I am SO sorry to send you (and me) on a wild goose chase.

What solved the problem for me was "overwrite the original" preference setting.

I have old non-GPS photos that I want to add EXIF GPS data, macOS Monterery V.12.3 and GraphicConverter 11.6. Permissions were correct, disk access was correct.

Problem solved for me. GC 4 EVR!

Thanks for the absolute BEST support.
