[Google Pixel 2 XL Questions & Answers] MrRussellLuther:
Hello, I'm trying to update my pixel 2xl to the latest Android 11 using Magisk Cannary 20426 and everytime I've tried to either patch boot.img or install the magisk,zip using TWP I'm getting this similar error in my `adb logcat`. I'm able to still aceess the phone after a failure to flash the new boot.img but flashing the stock. This means that I donot have root on my phone anymore.

Things I've tried:

Reinstalling the magisk app using cannary

different usb port / cable

updated platformtools

any advice to assist in debugging this would be greatly appreciated
