Working for me.
I suspect you have broken db or other in /data/adb due to unofficial Custom Magisk use if didn't take full Magisk Uninstall. I was able to take 'dirty' Alpha install (w/ Direct Install) over Canary however.
Also, to clarify, you will need to disable Enforce Denylist after you configure it as per original instructions. (Google translation could be clearer / doesn't help):
Clearly we will need to wait for Zygisk compatible solutions / details for other traces / environmental abnormalities detected. I have no idea how @nu11ptr got completely happy Momo.
Both Rootbeer Fresh and Rootbeer Sample are happy with my setup, and I can still hide 'root' from PushTAN app.
Edit: See you got it sorted...
Nb. Solution is not open sourced yet, and @nu11ptr indicated that this will likely not change.
