Hotshots flash issue, griii

Has anyone else had hot shoe issues on the gr iii. Mine seems to have stopped working and I can’t seem to figure out why. I’ve tried multiple different flashes (flash q20, flash q20ii, reflex labs Mimi flash, some godox flashes, all fully charged and working in other cameras ) I tried taking the hotshoe apart and cleaning it and still nothing. Can’t seem to find any information on similar issues and can’t find a solution

I’m hesitant to pay 400+$ to precision camera to fix an otherwise working camera
