Garry's Mod 'Start New Game' Crash

Whenever I click ‘Start New Game’ in Gmod, I go through the same old loading screen, but when the loading bar gets to ‘Initializing game data’ It pauses for a second, then crashes. I verified the cache and tried to find the addon that’s causing this, but had no luck. Here’s my .MDMP crash file link, if anyone could see which addon is doing this, That’d be great. Thanks

How many maps do you have?

Also, try disabling your addons; you’ve got a quite a few.

29 Maps. And you mean look for addons I don’t use and disable them?

Yeah

No; temporarily disable all workshop addons and put all of your legacy addons in another location.
