On Macbook Pro 13" M1 Diagnostic at startup does not work

Trying to run the diagnostic at startup, using the suggested method for Apple M1 chip. The diagnostic loader is not able to load and just keeps trying.

Does this mean you were never able to view the Diagnostic Codes?


Perhaps if you were able to restart in Safe mode, then start again

after about 15/20 minutes (to exit safe mode.) And startup as usual.
