Apex legends crashing without error

@OverlordZergI managed to find a temporary "solution" or at least one that worked for me. I had the exact same issues as you, I'd crash literally almost every single game. I've got the game running stable now and it has only crashed twice in the past 6+ hours (no error message, it just stops responding, but I dare say that could be an issuewith my PC since my CPU is constantly reaching in the mid 90 degress and thermal throttles) I've tried a combination of everything I can think of and nothing worked until I did this. What I did was literally just change from fullscreen to borderless windowed (Which I know you tried) but on top of that, I changed my Vsync to adaptive.. I can't explain how or why but I'm telling you now, ever since I changed the setting, my constant crashing has pretty much disappeared. I haven't done anything but but the same as you and rolled back my nvidia drivers (to 417.71) which seemed to work for a while but the issue just came back before I changed these settings, I've tried a combination of everything I can think of and these settings along with the old nvidia drivers has been all that has worked.
