Lua Panic

Lua Panic! Something went horribly wrong! " attempt to index a nil value"

when connecting to server

My Specs:

CPU: Intel i7 4770 @ 3.8MHz
Ram: 12GB of Kingston ddr3 @ 1066
GPU: EVGA Gefore GTX 750 w/ ACX Cooler
CPU Cooler: CoolerMaster Hyper 212 plus
PSU: Rosewill ARC-M 650w

That’s not specific enough. We don’t have where the actual error occurs.

The engine error does not show a stack trace unfortunately. It does happen in the menu state.

It is nothing to do with your PC, validate your GMod.

Is there a way to get a stack trace before it crashes with the error?

It occurs within frequent maps I think. I just joined a server that I never had a problem on and it just caused LUA Panics, then GMOD Crashes. I already validated GMOD several times, reinstalled and even cleared my workshop addons.
