GMod Crashes to Desktop whilst connecting to a server at the 'Sending Client info' stage of connection

I have had Gmod for sometime now but have rarely been able to go online, as stated in the title my Computer will crash at the sending client info stage.

Either:

LUA panic something went horribly wrong "not enough memory
or
Just crashes to desktop, no error message

I have tried the usual various times:
-adding ‘-heapsize 2097152’ to launch options
-Verify integrity
-re installing GMod
-Using a different account
-Removing and unsubbing from ALL addons

Any help would be appreciated, thanks in advance.

I’d be interesting in knowing of a fix as well. My computer back home does this all the time and if not i get 1-2 second ingame freezes every couple of seconds.

BUMP

Much Bump
