CS:GO Host Error Crash

[Squidward]

if it's consistent with a specific map, you could try deleting the map with an issue and just letting it redownload the next time it comes up? the files will be at (where have your steam library, mine is C:)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\maps

i'm not sure but you could try that

edit: you can go straight to the files if you go to ur steam library, right click on csgo, 'properties', 'local files' in the top tabs then 'browse local files'
