Rpi 4 2.90 Beta 14 stopped working after I plugged in a Victron usb to RS485 cable (connected to an ET112)

Everything was working find before this - I had a USB GPS dongle, RUUVI temperature sensor and a 500A smartshunt all connected and working fine for several weeks.

When I added the ET112 it all went offline. Removing it doesn't work. I've plugged in an HDMI screen and all I see is the victron energy BLUE POWER screen, and a cursor.

No response to a usb keyboard.

Is there anything I can do to find out what happened? Or the only thing I can do is reflash the SD card and start again?

It appears not to be connect either to WiFi or ethernet :(

Thanks,

/Simon

It turned out the SD card had corrupted itself (probably due to power off/on) at the same time I plugged the ET112 in. Fresh install on a new SD card and everything is working.
