for a start, at least drive off the mats
Yes and it must be done fast. Please do not hesitate and do it fast before this resistance will degrade further. It will soon blow a mosfet / power-stage when the resistance drops below 5.
I had such card 1080ti mini which started from 32 ohms (it should be a 100). When the mosfet had blown I removed mosfet, measured and it was between 3 and 4 ohms. It looks like GPU. Remove GPU first and measure on the GPU's capacitors. In general it can be both VRAM and GPU together.
Thermal cam would show you that the borders of the GPU are hotter. Look at the color around GPU, maybe it is already brown. Please post a close picture...
