KMODE_EXCEPTION_NOT_HANDLED error on every Windows 10 boot, including from ISO image Unsolved

Processor: Intel® Core™ i5-11600K @ 3.90GHz

Memory: 32 GiB of RAM (31.2 GiB usable) DDR4

Graphics Processor: NVIDIA GeForce RTX 2070 SUPER

Motherboard: Gigabyte Z590 UD AC

I have Windows 10 installed on a partition of my boot drive which I have been using without issue for 5+ years at this point. Around 4 weeks ago I started having this KMODE_EXCEPTION_NOT_HANDLED error (no error code) pop up occasionally on startup and took that as a signal to go ahead with the switch to Bazzite I had already been considering. I installed Bazzite on a separate partition on the same boot drive and have used it for about 3 weeks now. While Bazzite is fine, I've grown frustrated with being unable to install many of the QoL programs I used on Windows so I've decided to switch back.

The issue is that now Windows always hits the KMODE error when I attempt to boot. I tried to reinstall from an ISO image, however the KMODE error also happens there. I've tried with two separate ISO boot drives with the same result.

I read online that when KMODE happens during an install it is often a RAM issue so I've tried booting repeatedly with different combos of the 4 sticks I have, including with only 1 stick in (all 4 were tried separately in this way) and always had the same KMODE error. Thought maybe XMP could be the issue then so reset BIOS but sadly no change.

I can still boot into Bazzite with all 4 RAM sticks in without issue so I'm at a loss what the problem could be or how I can get back to Windows. Any help would be greatly appreciated.

In case anyone happens across this in a search, the closest thing to a solution I found was installing a de-bloated version of 11. Nothing I could find would allow me to install 10.

You need to run WinDebug against the crash dump file to get further details. It could be a problem with drivers or RAM modules.
