I?ve done this now more than 2 dozen times. Everything works fine, until I install NetHunter. Then it boot loops.
I have installed the correct Android 10 compatible Version of TWRP 3.3.1.0
I have installed Magisk, and disabled DM-Verity and Force Encryption. This was done after installing LineageOS, but before initial boot.
NetHunter was installed after initial boot and I completed the device setup before attempting to install NetHunter.
I verified the FS before installing NetHunter zip package, and determined there was none.
I verified the FS after installing NetHunter zip package, and found unrepairable damage.
There were no reboots in between FS checks or installation of NetHunter.

I am trying to attach the log file from TWRP to this message, but I am being told ?invalid file?.
