I just had the same issue on an XT3 with a camera that's less than a month old. I have the battery grip. I just unscrewed it and the freezing stopped without having to take the internal battery out. I screwed the grip back on and went back to shooting. It's quite disheartening, though. I hope Fuji deals with this. I also was shooting Godox xpro trigger. I noticed a few people mentioned they were shooting flash when it froze. I'm not sure if it's pertinent, but I thought I'd mention it in case Fuji is monitoring these threads.
