Same here with the 07/03/21 build. Did you resolve it, and how ?
Flashing the zip again from recovery and deleting the caches did nothing as well.
SOLUTION: After uninstalling MAGISK the phone booted into the OS.
UPDATE: It is the cusom ANX Camera modules - i added them back, and the same thing happens. It worked perfectly on 1/3/21 build :/.
BETTER SOLUTION: In recovery go to /data/adb/modules/ and delete the 2 anxcamera files/folders.
Bah the ANXcamera worked perfectly before
. Might downgrade to the build where it worked. Does anyone if I can download the old 1.3.2021 build ? Being a moron i deleted it from my phone and the download page only shows the latest.
