I did a webUI upgrade yesterday and exported/imported my rules over. Ran it for a few hours with the Dashboard open and saw no issues, even after a few reboots.
Went to bed 3am, woke up at 9am and the router stopped routing. Using the VGA port for display, I logged in locally and tried to reboot. Got the option menu to reboot or restore, etc. Selected reboot, started to and hung.
Never rebooted, so I had to hard shutdown the router. Upon coming back up, it couldn't find a library and asked for a location and I choose default. Stopped right there. Worst upgrade of Opnsense I ever experienced in the last year of using Opnsense.
Wiped everything this morning and restored to my config backup of 25.7.11
This is the hardware in question:

Sorry I don't have more complete info or logs. I had a migraine this morning and just wanted to brute force fix it asap.
