might as well start off by stating the obvious: actually look at what addons you're executing and disable things you don't use.
stuff like this:
- disable Ai_national socialist, it's looking for Gamemode_zombie, which you don't have
- disable Event_DamageCreep, it's looking for Gamemode_Creeper, which you don't have
- disable Event_Parachute, it's looking for Item_Parachute, which you don't have
- disable Event_ZapkSound, it's trying to use another addon that was CRC'd for injection vulnerabilities and probably doesn't even work right now
- disable your gamemode addons, you have Gamemode_Speedkart, and Gamemode_Rampage attempting to load (Rampage manages to stop itself, but disable it anyways)
- if you're not running a dedicated server, Script_Eval is pretty much useless
- disable Vehicle_Luton_Van, it's looking for Support_Interactive_Vehicle, which you don't have
if that doesn't fix things, disable the addons you most recently enabled/downloaded
