BOOTLOOPED my phone after running magisk! Please help me recover. TWRP still works.
My Nord 2 is stuck in a bootloop; VERY new user here so definitely appreciate any help immensely, androids and rooting phones is totally alien to me; and this is probably the most stressful thing I've dealt with in a LONG time.

TL;DR
I was running a rooted .A11 update just fine, updated to .A12 following a guide, lost root access, so re rooted phone just like i originally did. Got to the point where i used TWRP to flash magisk.zip, that part worked fine, phone booted just fine, launched the magisk app from the app drawer, let magisk install full version, it automatically rebooted, then immediately got stuck in a bootloop.


Full story for troubleshooting context: (in case you can see where I goofed)
- I updated from .A11 to .A12 successfully which meant the phone was unrooted; Followed @pankspoo 's guide except using my own OTA update.zip after clicking download in my settings app (I'm EU region); https://forum.xda-developers.com/t/...rooted-nord-2-any-incremental-update.4347813/ (following the comment to find the update.zip folder at /data/OTA-package/update.zip
- Verified my phone was fine running the .A12 update properly; opened settings app, checked about phone page, .A12 listed and "newest version installed". Launched the root checker app and confirmed phone was "not rooted" anymore so proceeded to follow @pankspoo root guide again https://forum.xda-developers.com/t/tutorial-twrp-and-root-nord-2.4340477/ , the same guide I originally used successfully back on .A11 (worked great!)
- Got to the point in the guide where I flashed and installed TWRP, it worked just fine. Nothing unusual so far.
- Used TWRP to flash magisk.zip, also worked fine. Still nothing unusual.
- Used TWRP to make a full backup (ticked all boxes) here, but this backup file seems to be GONE (did not transfer it to PC)
- Rebooted to system, phone booted just fine, found magisk icon in the app drawer, launched the magisk app and let it do its first time setup thingy, where it "installs full magisk" and so on. I let it do it's thing, eventually it rebooted the phone;
- Phone now immediately stuck in bootloop. Don't know if Magisk even installed itself properly; Waited out the first bootloop long enough that the phone ended up rebooting multiple times and ended up automatically booting into TWRP so its not a "just wait longer" issue.


Symptoms:
Its a standard bootloop aka stuck on 2 rotating white dots around the larger red dot. If i wait longer enough, phone reboots, initially shows the 1+ icon and the "orange state not trusted boot in 5" message that we're probably all used to seeing. After a few reboots it eventually ends up booting into TWRP.

Holding Volume up+power forces the phone to reboot, but obviously, still gets stuck in the same bootloop.
Holding Volume down+power when the phone reboots places the phone into fastboot mode, which lets me connect my computer, open the powershell window, and use the "fastboot reboot recovery" command to get into TWRP instantly.

TWRP is working fine! I can still flash things and do all the normal stuff in TWRP... But not idea what to do right now.


Stuff I've already tried: (against my better judgement)
-Clicked "restore" button on TWRP; I made a TWRP backup ticking all boxes like 10 minutes before the bootloop issue started; Right after I used TWRP to flash magisk.zip successfully; However, my NORD 2/Internal Storage/TWRP folder is currently empty; There is no backup folder there! I did not transfer it to my computer so no idea where it went.
-renamed magisk.zip file to uninstall.zip and used TWRP to flash it; Nothing seems to have happened. I did read the text on the phone and saw a bit saying "magisk will not be uninstalled please uninstall manually" so i guess something went wrong.
-Tried reflashing magisk.zip normally.
-Remembered I made a TWRP backup a few weeks ago, so used TWRP's Restore feature to restore to that backup. This is a backup was when the phone was running .A11 and obviously working fine, not sure if that matters much. (didn't help either so I assume TWRP backups don't restore stock os or anything like i thought it did?)


Obviously, none of the above resolved the boot loop and I have no idea what to do from here. Phone still stuck in the same old rotating 2 white dots around the larger red dot animation.


Not sure if I should reflashed anything at all as I'm pretty inexperienced. Scared to try anything else without consulting you guys for help first. Most google results for bootloop fixes seem super sketch and outdated so I'm scared to try much else, and already thinking I may have made things worse with the things I did already do.


How do I proceed from here? All help appreciated. Not sure if using .A12 was the wrong call here but i suspect it was.
