Broken UI, Possible Kernel Panic?

My UnRaid Web UI is hideously broken.

The following tabs don't load at all: Dashboard, Docker, VMs
The following tabs are majorly broken: Main (no controls, just list of disks), Plugins (some of the menu loads, then infinite loads when trying to update the plugins)

 

In trying to diagnose this, I've had to do a few unclean shutdowns, just because UnRAID is giving me no other tools to work with the server.

 

The only notable thing in the System logs is this message on boot:

EDIT: After trying to create diagnostics, I saw this new error

Is this using GUI mode on the server itself? Or using a browser on another computer on your network?

 

If on your network, do you have any adblockers? Have you tried clearing browser cache? Have you tried another browser?

 

Why are you running such an old version of Unraid?

My unraid tab at the top lists my version as 6.5.2 so its not that old, this problem has survived disabling adblock and going incognito. I'm using a browser on another computer on the network.

Oh, I get it. Then I change my question.

 

Why did you post 2 year old diagnostics?

I honestly don't know. I hit the download diagnostics button before posting, and that's what it gave me. Along with the second console error that I added to the OP.

I'm going to be trying a direct connection in an hour or so, we'll see what that gets me.

Worst comes to worst, what's my nuclear option for resetting unraid without affecting the data on the array?

If you aren't writing to the array then hard power down isn't likely to affect data, but you will get a parity check due to unclean shutdown.

I got it sorted out. Once I brought out my VGA monitor and keyboard/mouse to debug it correctly, I was able to boot into GUI safemode, delete all my plugins except CA, and restart. Complete success.
