Game suddenly crashes after 3min

For a few days the game has been perfectly fine, but suddenly one day I open the game and it crashes, when I opened the game back up I got a texture pack error then after that the game has been crashing ever since  

I tried resetting the console, I tried reinstalling the game, I also tried rebuilding data base but it still didn’t work 

if there is something else I need to do please let me know, I’ve been having a lot of fun on this game till now
