USB-C ports broken after 11.2 update

Both of my USB-C/Thunderbolt ports on my M1 Mac mini have become completely unresponsive after installing the macOS 11.2 update today.

I had a USB-C to DisplayPort cable in one and a USB-C hub in the other, neither of which now functions.

Both USB-A ports, the Ethernet port and HDMI port are functioning fine. Anyone come across this or have any ideas on what I can do? I've run the diagnostics tool to no avail.

Thanks in advance for any help.

Mac mini, macOS 11.2

Is there any way to DFU without thunderbolt?

I have the IPSW file, Im just not sure if its loadable through other means.

Only that one port :( in hindsight it would have been super useful to have a usb-a port available for DFU. do you want to try the “erase Mac” downgrade to 11.1 test?
