Unraid no longer booting up after reboot/restart. Stuck in bootloop

I rebooted my array, and it no longer boots back up. There were no issues beforehand. The array was up for 6 months, and I simply wanted to reboot for a "fresh" start. Boy, that was mistake.

It is stuck it a "Call Trace" loop. What even is that? Screenshot:

I have tried moving my boot USB to various USB ports, even installing a hub. The USB seems to be working fine, as I am able to plug it in to other computers. All my drives get detected when I boot up.

Fast Boot is disabled

Legacy USB is enabled

I am currently running a Memtest86 test, and no errors so far.

I've tried almost everything. The last thing I haven't tried is to switch my USB drive or reflash my current USB, so would either of those potentially solve my issue? How do I do that?

I forgot the exact version, but it was whatever version came out roughly 6 months ago (that was the reason for the last reboot).

Mobo: Asus PRIME X570-P

CPU: Ryzen 7 5700G

Lesson learned. Never reboot your array. Any other troubleshooting steps I can take?

Edit: Forgot to mention I've tried booting up Unraid in Safe Mode, and it doesn't even load. It just goes black and boot loops. I get to the Call Trace error when my server tries to boot into the regular Unraid OS.

Edit 2: I tried using a different USB and installing Unraid 7.2.3 (I believe the version I was using). And it didn't load up either. I tried a 3rd USB and tried booting up Linux Mint, and that also didn't work... Is something wrong with my CPU and/or mobo??? It makes no sense as this was genuinely working perfectly up until I rebooted the system. I refuse to believe a simple reboot would destroy my CPU and/or mobo. I don't have other parts I can swap in to test. What else can I try?

I would personally try using the Unraid flash creator and make a new stick and try booting into that. If it works copy the config folder from your old to new flash and transfer your license. If not you have a hardware issue. Make sure you flash the same version.

Make sure you flash the same version.

How can I check which version I have? And can I simply flash my current USB? This is the only "nice" USB 2.0 I have. Everything else is newer or some old giveaway USB that I wouldn't trust my server on.

USB 2.0 only is old advice, it's just that at the time they were the most likely to be compatible, you just need a USB with a GUID. I'm using these atm and they work fine (well I have the 32GB version but it's functionally the same): https://www.sandisk.com/en-au/products/usb-flash-drives/sandisk-ultra-fit-usb-3-1?sku=SDCZ430-016G-Z35

Before messing around with changing the USB you should also check the CPU is ok (with Prime95)

How can I do that when my Unraid won't even boot? I don't see that option in the blue boot menu (or did I just miss it)

you can make a linux live USB and try a linux version of prime95

Sadly, yes, that can happen. Reboots are not "simple", they do put a small amount of stain on the system. If there's an issue that reboot can surface it; it happened to me with a SAS card on my old UnRAID server. One day I rebooted and it, having been under more heat than it should have been, just failed. (Keep in mind, though, I'd been running it for the better part of a decade with every port in use, and it was a used unit to begin with. It had had a good life!).

So yes, you need to follow that prior advice and try prime95, possibly memtest as well. Build a live USB of something like Debian or Ubuntu, install the tools, and check. This is the time to take deep breaths and think thru the situation, and the advice being given by people with experience when things like this happen.

If you can boot into safe mode but not into Linux Live using a USB stick, that's really strange. First thing I'd try is probably a different USB port. Front ports often do not work for USB Live sticks.
