As the title says, game randomly at times goes black screen, like it kicks me out of full screen for a sec and freezes but I can still hear the game still running. Sound is still going, can hear the NPC talking or my character fighting if I click and get damaged.

I checked my specs and my PC is WAY more than enough to run it so its not that. It's not my antivirus as I tried it without it. All drivers are updated. Can run other games on ultra with no issue.

I'm using PSO2 Tweaker and I tried all the troubleshooting with it and it's still happening. Happens in both full screen and windowed mode.

Not sure what's causing this and would please like some help on what to do to fix this.
