I loaded in the map with the blue light gamemode applied and https://steamcommunity.com/sharedfiles/filedetails/?id=2969936513 it just puts me in this room

Turn off all other mods and restart the game

Or show to me what was printed in the console

disabling all mods worked though, thanks

You're welcome!

While we we're playing co operative with my friend Whenever the start chapter 1 his gmod crashes EVEN WITH ALL MODS DISABLED
my friend : https://steamcommunity.com/profiles/76561198084343245/

yeahh uhh help

Hi! I do not know the reason.
1) When the map is launched, can you run together?
2) or does it just connect, the game crashes right away?
3) Does your friend have an old computer?

case A:
If your friend has not turned off the mods on his side, then sometimes this can have a bad effect on the game.
Solution: turn off all mods and restart the game, also check crash in single player

case B:
The problem may be in the amount of different content that your friend could download from different servers
Solution: rename the Garrysmod/garrysmod/download folder to something else (like "2download") and restart the game

case C:
There is also a feature that my mod forcibly includes gmod_mcore_test, which gives increased FPS due to multithreading, but it is written that it is unstable
Solution: go to gm_construct in a regular sandbox and enter gmod_mcore_test 1 into the console. If the game breaks after that, let me know, I will update the mod soon

case D:
You can also check if the problem is in the mod or in the map.
Solution: Select Blue Light mode and run on gm_construct. Reverse situation: run on my map in a regular sandbox

If you or your friend can make a video showing exactly where the game crashes, that would be great!

case a was already done.
Reply for the first question : I Don't get it i don't speak english too much
Reply for the second question : the game crashes right away (his gmod crashes not the whole server)
Reply for the third question : Nah he uses WIN 11
Reply for case b : We tried to fix it by disabling all the mods, like quick slide, kick, quicknade. Didn't work ):
reply for case c : I'll try that. I'll keep you updated.
I Also didn't understand case d lol
It crashed at where the chapter 1 starts. you know the door with a locker of medkits and a SMG

case d will help you determine if the problem is in the gamemode or in the map.
Your friend needs to turn on the Sandbox gamemode and play the bl_blue_light_c1m1 map. Then you need to fly out of the room and inspect the entire level
If the game is not crashes, it may not be the map problem

Need more details:
1) Before the game crashes, your friend must copy (or screenshot) the entire contents of the console. Sometimes there is useful information
2) At what point does the game crash? You just walked up to the door and the game crashed? Did you turn the lever and the game crashed? Did you fully open the doors and go further into the tunnel and the game crashes?

You can also try doing the following:
case e:
You create a server, start the game and shoot at the first enemies. Your friend joins the server in the middle of the game.
If it works, at least you'll be able to play together.

English is not my native language :)

The game crashed whenever he walked into the door

thanks. i'll try case e.

same, english is not my native language too.
