So, if your csgo is crashing (2018 version) there are 2 ways to fix this.
The first one is easier if you have 2 monitors.
1. So when u startup csgo, u wanna inject the "csgo_2018_fix.dll" into csgo with process hacker. You must do this pretty quickly.
2. This is an easier method. You wanna replace the "client.dll" in F:\Program Files (x86)\Steam\steamapps\common\2k18csgo\csgo\bin (your 2018 csgo folder)
with the "client.dll" that you gonna download from here.
Simple as that!
Hope this helps to some ppl.
