Hi, sorry for the late reply. I was quite busy back then.
Anyway, here's the [CRASH] Accelerator uploaded crash dump: Crash ID: HWT3-ALYP-4G7A

And about the "enable plugin one by one" part.
I tried it, but I'm still confused about which plugin is causing the game to crash and send me back to the main menu.
For example, when I disable one of the plugins, everything works fine. However, when I reopen L4D2 and play, it crashes and forces me back to the main menu after the loading screen.

Edit: Okay, Somehow manage to fix myself by completely uninstall l4d2(including sourcemod and their cfg, data, etc) and install l4d2, sourcemod and metamod again. It took half of month to solve this
