Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Code:
#include <std_disclaimer.h>
/*
 *
 * We are not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if
 * you point the finger at us for messing up your device, we will laugh at you.
 *
 */

1. BlissOS latest GSI with device PIN selected during setup:
Data partition shows as 0mb in TWRP and asks for password to decrypt. Can't decrypt it with selected phone PIN.
Removing PIN from phone did not help either (still asked for password)

2. phh-AOSP 9v114 with device PIN and secure start-up selected during setup:
Data partition asks for pattern(?) to unlock in TWRP, even though pattern was not set.
Also the header at the top changes/flashes colors when on pattern screen.

3. Factory reset and setup with PIN but with secure start-up disabled:
This time it doesn't ask for pattern but password again. And can't decrypt with PIN.

4 .Factory reset again and setup without any kind of pin/pattern/password.
TWRP still asks for password to decrypt data.

5. Factory reset and setup pattern
TWRP asks for password

6. Repeat steps but this time with stock ROM from Umidigi. Same problems.

Code:
E:Decrypt took too long, killing process
Failed to decrypt data.
Unable to decrypt with default password. You may need to perform a Format Data
Unable to mount storage
Unable to mount /data/media/TWRP/.twrps

was having trouble with forced encryption on stock rom but finally got past it
Why not share your solution?

So you just flashed Magisk over stock ROM if I understand correctly from that post?
You say you flashed disable dm-verity but after that you restored from a full backup. That means the disable dm-verity package was removed anyway.

I tried flashing Magisk as well and even disabling persist force encrypt in Magisk app but that didn't solve my issue.

In any case I would like to be able to backup my data partition without flashing magisk and disable dm verity forceencrypt, simply by entering the password I set in Android.
That is how it is supposed to work anyway from my understanding.

Yes.lol...i know that's what's so crazy.i gave up trying when I flashed the backup and just flashed magisk maybe something got left behind that didn't get wiped I don't know.i was shocked when I checked in settings/security and phone not encrypted. Rebooted to recovery and no password prompt all storage visible.
