As I have said many times before in this thread.
Just because you've played for a couple of matches/hours without crashing doesn't mean you've fixed it. Two days ago I actually went a full day and a half, about seven hours of play time, without crashing. Without changing a thing. Without doing any of these "fixes". It's random. Sometimes you will get lucky.
This is not likely something that WE can fix with silly tinkering or messing with our configs. This is something Respawn/EA has to fix, or Nvidia. Or Radeon in the few cases where someone has one of those cards. And as said, a new Nvidia driver came out today that has the name of "DX11 performance". So who knows.
I tried the new driver before I downgraded the .Net to 4.0
