How to fix firmware stuck on "Launching Applications"?

Question

Android

Tablet model: Nexus 7 2013 Wifi (flo)
I decided to install Kali NetHunter. Download everything you need.
Installed TWRP
I'm already going to install 6.0.1 Android (from MoHaMaD-RoM). Put. I'm launching.
Then the "Android starting" window opens. Applications are being optimized.
After optimization, hangs on the start of applications ("starting apps")
On 7.0, 8.0 (7.0 - CM, 8.0 - Lineage) everything works successfully. Android starting doesn't even show up.
Only 6.0 is "buggy". Versions < 6.0 did not try.
Backups naturally exist.
Bootloader version : 04.08
TWRP version: 3.2.3-0 (I do not think that it affects, because it is successfully flashed)

I tried a lot of custom ROMs, none of them started successfully.
I download firmware from XDA or w3bsit3-dns.com
Help please, this is urgent.
