Did you flash the magisk patched image right away or did you flash it at the end?I went ahead and flashed. That was less fun than I wanted today. I had to do a full flash-all to both slots to get rid of the mess of the slots. I ended up using the c3 build that Google posted yesterday. Just a heads up if anyone does the same. You cannot use the patched boot included with this ROM. You will need to install MM, and patch the boot from c3. I am up and installed/rooted. Now to set everything back up. Thanks for getting this out there @slothdabski.
Most of the time I'm unable to get into fastbootd to flash the system and product images if I flashed the magisk patch boot image.
This can be avoided by flashing the regular unpatched boot.img when doing the first step of flashing boot, vbmeta, and dtbo.
Once you reboot into fastbootd to flash system and product, you can then flash the magisk patched boot img and everything should work.
Someone please tag me if this procedure is followed and you are still having issues with the magisk patched image
