Apex legends crashing without error

Both my friend (rx 580, i5 8350k) and me (gtx 1070ti, i5 8600k) tried the "+fps_max 100" line and it still keeps crashing. Later in the day we will try to adjust the virtual memory. I also heard somewhere that increasing the FOV (filed of view) causes crashes, so it's best to set video settings to default.

Things we tried that didn't work for us:

- disable GPU, CPU and RAM OC

- set everything to low

- reinstall game to SSD/HDD

- install latest BIOS

- windowed mode/borderless window mode

- set apex compatibility to windows 7 (we have windows 10)

- disable full screen optimisation

- reinstall/repair game/origin

- repair anti cheat

- try out both 1803 and 1809 windows builds

- he tried out 3-4 latest AMD drivers, I tried out 3 latest Nvidia drivers

- disable all background overlays, after that we disabled all those apps (discord, msi afterburner,...)

- disable origin in-game and overlay together with the overlay exclusively for apex in the game settings menu inside origin

- set origin/apex to run as administrator

- in the Nvidia drivers i set apex power management mode to high performance, maximum pre-rendered frames to 1, enable all cuda cores, enabled threaded optimisation, turned v-sync on/off

- can't remember anything else...
