it solved! Thx a lot!!
This answer helped. I can run for M1 Mac as iPad with Rosetta OFF. The rest of my workflow is with Rosetta ON.
Somewhere, somehow, this setting changed, or its ability to run changed. Whatever the case may be, I was working on an app a few months ago, would run it on "My Mac" perfectly fine the whole time when developing. Came back to work on the app, spent many hours dealing with provisioning, adding my device, recreating certs, profiles, blah blah blah with no success. Come to find out a simple "turn off and turn on" method is the solution after a good 3 hours. I could be sick right now.
This actually worked. I had one device registered with hardware UDID but with Rosetta2 off, it registered and additional device w/a different ID and now things are working.
For me I needed to restart Xcode, clean the build folder, make sure the "My Mac (Designed for iPad)" is the selected device, then go to the target's settings screen > Signing & Capabilities, where a button was now visible to "Register Device".
