Larkbox Pro - HDMI connection stopped working?

Not sure what happened but after 2 days of use, the Larkbox Pro no longer seems to be outputting out to HDMI. Tried this on a monitor, and a smart tv, despite the blue light power indicator on, I can’t seem to get any response from the thing. Keyboard and mouse LEDs don’t seem to be turning on even when being plugged in.

Have i been screwed over by Chuwi? lol
