I have a computer running Ubuntu 20.04 that appears to boot just fine until it makes it to the desktop. The boot process seems normal and the desktop loads initially, but after 5 to 10 seconds sitting on the desktop the screen flashes and goes black. After that point the system becomes completely unresponsive.
Once the screen goes black I lose the ability to SSH into the system, I can't pull up another terminal on the machine itself (Ctrl+Alt+F2, F3 etc), and the only way to restart it is to hold down the power button twice or physically remove power to the system.
The part that really makes this confusing is that the system works normally in recovery mode. I can boot the system to recovery mode, start a terminal to run startx and use it indefinitely. There are no issues with the screen going black, the networking shutting off, or the other terminals launching.
I've already tried reinstalling gdm3 as well as ubuntu-desktop, I've tried updating packages and fixing broken packages from recovery mode, and I've even used recovery mode to reset the grub loader options.
I'm assuming there's some barrier between what regular desktop mode does and what recovery mode does, but I'm not sure where to start when figuring that out. Any help on the matter or even suggestions of what packages have control over blacking out the screen/locking down the system would be greatly appreciated.
EDIT: It appears there are two separate desktops being launched at the same time. Both tty1 and tty2 (Ctrl+Alt+F1 and Ctrl+Alt+F2) have a desktop launched on them when the computer first starts up. tty1 launches to a lock/user selection screen, and tty2 launches to a logged-in desktop for my default user (which is the behavior I have configured).
EDIT 2: For context, the system is a desktop PC running a Ryzen 3 2200g and the iGPU from that chip on a Gigabyte B350 board. It's an install of Ubuntu I've had since about 2018. Adding some logs from /var/log/syslog from one of the recent boot ups into recovery mode. I'm seeing a lot of repetitions of this loop:

That doesn't appear in the normal boot cycle though, but I do see duplicates of what looks like the GPU boot process:
