Fortnite Crashing

When I play I just crash. No FPS drop, no nothing. The Performance is good, but I just crash. The crashing came with the 3.3 update, and I played since December. Never happened before. I tried everything. I uninstalled and installed again. It stopped, but than the crashing just continued. I also crash on loading a lot of times. So when I open task manager, it often crashes when the disk is 100%**. I deleted everything from my pc. Like steam and stuff. IDK WHAT TO DO, HELP! I do think this is going to stop on the next update. HELP ME!
