Gmod crashing on starting LUA

[stone nest]

So as tittle says gmod crashes i tried no mods, verifying game files, making exception in firewall none of those things works
but i found strange line in my console after i start game which is:

Attempting to load Chromium...
CLocalizedStringTable::AddFile() failed to load file "resource/garrysmod_polish.txt".
x86-64: gmod_mcore_test=1
Parent cvar in server.dll not allowed (p2p_enabled)

And after crash in my friend (host) console it says: Dopped XXXXXX(name) from server (XXXXX timed out)

What you were doing when the crash happened? Nothing just waiting for game to join me.
Can you make it crash again? If so, how? Yes it basically crashes every time i join on starting LUA and LUA started part.
Does it crash on all maps? Yes
Does it crash in singleplayer / multiplayer / both? Only when i join my friend server with other 3 friends and only for me game doesn't work. Singleplayer and Multiplayer like browser servers are fine.
Does it crash without any addons? Yes

Looks like some mod your friend has installed is running a command on your game (r_flushlod) that causes the crash

Do you maybe have idea which category this mod can be or maybe more details ?

maybe one of those "optimzation" mods, or anything to do with models
