UE4 fatal error - online

Ive tried everything to solve this but still no success. I got this error/crash since Halo 3 launch. First the game crashed on halo Reach, then halo 3, never on HCE nor H2. Single player always run without crashing. This continued until ODST launch, making my machine unusable for 5 minutes after the crash, and showing the UE4 “HUNG” error. Super annoying. Nvidia drivers updated 2 times since then.
A few days ago, the game got an auto update and crashes stopped but matchmaking got bugged because took forever on BTB playlists, only can join 4vs4 slayer. I just leave it there thinking the problem got solved but yesterday crashes returns at online matches. Unninstalled and Reinstalled on brand new sdd. Nothing.
I got this info from the event logger on w10. I have the Windows Store version of software.
