Flash back the original boot.img (w/o magisk) and reboot
Code once in fastboot mode:
“fastboot flash Original_boot.img” (use the “Original_boot.img” from the above zip file)
Change to the exact name “Original_boot.img” of the boot that has been posted in the above zip file
“fastboot reboot”

If you can still go to Settings:
Flash back the OTA RUU full package and reboot
Option 4 – Change the active slot
If your device can go to fastboot mode:

Then just change to the other slot with the following command:
“fastboot –set-active=a”
or
“fastboot –set-active=b”
Then reboot with the command:
“fastboot reboot”
