Symptoms

Entire AMD GPU driver completely crashes in game. Can be reproduced consistently, but also happens seemingly at random. Lucky if I get to play one match before this happens.

Reproduction

Can be immediately reproduced by running to the back of the Lobby / Hub area and interacting with the Horizine Tech pile a few times. Game then freezes, and screen blacks out as the GPU Driver refreshes itself. Then Steam will fully close and the game will crash alongside it.

Can see that it crashed by using dmesg

Where is this "horizine scrap pile" in the game, and how do you get to it? How much of the game needs to be progressed to be able to reproduce?

@HansKristian-Work

It's at the back of the lobby / hub area. Easiest way to find it is to go up to the VTOL (Helicopter) and behind it on the floor past the platform, there is a pile of scrap items that you can interact with by a forklift. When your crosshair hovers it, it will be labeled Horizine Tech. You can interact with it a few times (which will bring up a popup menu simply saying "Horizine is always watching. Make sure to destroy their tech" or something along those lines, and a button to close it). Sometimes it crashes on the first time, others it doesnt. But if you interact with it a few times in a row it will consistently reproduce.

I'm not sure about how much progression is needed, but I've leveled the Firebug perk up to about level 22, the rest are all at about level 1.

There is a video of where to go, and it happening. The video didnt capture all of it, but I opened and closed that dialog about 3 times before it fully crashed the driver.

Here is another log of that play session if needed.
