[2020] Crashing to desktop for almost a month now

Gents and gent-ettes, help me out here.

I've been running PS2 on low-medium settings and I have experienced odd crashes. The game seems to freeze up for the briefest of moments and then closes without any error. Once or twice the game has also opened my Chrome and redirected me to the ''Game Error G12'' page.

I am running a i7-8700k with 16GB of 2400 DDR4 RAM. Processor used to be manually overclocked, but now is running at stock speeds + whatever boost the motherboard applies in its High performance bios setting. Change was done as a part of troubleshooting.

ROG STRIX Z370-H mobo with a 1070 GTX, later changed to a GTX 2070.

Latest changes included a full system reinstall.

As a part of the test, Windows Gaming, Discord and Steam overlays all are disabled. PS2 Steam Version, everything running as admin.

I have also attempted to cap the framerate via RivaTuner that comes as a part of MSI Afterburner. Also tried running with and without MSI Afterburner installed on the system.

I am just kind of out of ideas at this point. The game usually crashes two or three times with small intervals, then remains stable for a hour, only to start crashing again. Does not seem to be impacted by battle size or continent.

I really could use your help on this as I cannot lead any squads if I risk getting booted all the time.
