Hi, were you able to solve this? got the same issue using latest version, clean flash, etc and get the exact same symptoms.The latest OTA update seems to work fine. One major problem though.
I tried to reinstall Magisk after the update, via ordinarily patching boot.img of the newest ROM. After flashing the Magisk patched boot img, CrDroid boot screen arrives to the rainbow eye which continues in loop without loading the sys. I had to roll back to the initial boot.img and thus lost the root.
Has anybody else experimented the same issue? Did you find a solution for it?
Edit: symptoms go a bit further from the above in fact. I was able to install magisk, rebooted, flashed the boot image, rebooted, everything went fine... I flashed another module, rebooted, went well... Turned off the phone and only then it got stuck into a loop (the crdroid eye).
Flashed the original boot.img and no more bootloop, but no more root either! In my case it all hinges on the module I installed. cdDroid works normally.
