I suspect it is a GU10 bulb and you have broken it by trying to unscrew it.
See step 4.

Did the bulb and the fan stop working at exactly the same time? It might have blown an internal fuse caused by the power surge, but it's odd that the other bulb still works.
Can be replaced with 5w led gu10, if you have one working light then you have power, has fan ever worked?
Probably needs replacement, do you know make,model?,,) ,
Yeah it stopped a month ago. It was in the flat when I moved in three yrs ago
Probably needs replacement, do you know make,model?
does it have an extractor duct through the wall or ceiling? older ones were often 100mm but they're now usually 125mm or 150mm
If the filters were clogged that might have caused overheating
look at your motor casing in case there is a red reset button on it.
there should be a paper, foam or tight metal mesh to catch the grease, and there may be a charcoal filter to absorb odours. The charcoal ones I've seen are black plastic with an absorbent face, around ten inches in diameter and and inch or two thick, on the intake to the motor fan.
