Tx power dropped to 0.02W. SWR fine 1.5-1.8

I was using cat control over USB for 20m FT8, I also had a 12v power supply 1A. I was running the board for about an hour. Flicking between FT8 and WSPR, getting about 1.5W out registering on the board display with ~1.8swr when Txing.
I then noticed all of sudden that the board was showing 0.02W on Tx with 1.8SWR. I tried removing the power supply and running usb only but same power output.
I've seen suggestions of the MOSFETs being the issue but I took a look at them and no obvious signs of burning out. Would they be obviously damaged?
