Symptoms

The game crashes on the newly released Louisiana DLC. It crashes around the city of Alexandria, either on the southern part of the town (More specifically, the street that links up the EPR, Equos Energy and Chuck's and Jack's depots), or just outside of it, at the junction of US-165 and US-84.

Reproduction

1. Create a new profile. (You can use an existing one if you want, this is just to confirm that the crashes aren't mod related).
2. Select Alexandria as your starting city.
3. Drive to one of the above mentioned spots (or use freecam) and the game should crash.

Other stuff to note:

• The crashes do not occur when playing the game using the acutal Linux version with Proton disabled. (However, the Proton version is superior to the actual Linux version, so a fix would be nice.)
• An another non-Windows user using Proton experienced the same crashes at the same spots, so that's how I was able to figure out the crashes are Proton-related.
• SCS (the devs) behind the game, confirmed that they do not support Proton and will not fix this issue themselves.
