Hello , this may be problem with your addons, try disabling all of your addons first, if that doesn't work you can try to launch the map via console ("map gm_mines"). If the problem persist then try to verify the integrity of game cache.

I played a map with my friend and it worked fine but when I try it it happens so this IS a addon problem. I have over 1000 mods so it's close to impossible to track down the one that's doing this. BUT. I found that when it kicks me the console gives me a few things. all of the text aside from the scp 294 text is white. the scp 294 mod's text is green. It's probably not realated but I'll do it just in case

This looks like the map has too many decals, so it shuts itself down. The map, however, has very few decals, so it's a problem with your addons. From what I've found, some people claimed it may be the "Extended Paint Tool" mod.
