Hello everybody ! this will be focused on some of you that has some gmod errors and your gmod crashes everytime when you are loading the map...and im here to help you avoid the really often crashes.
LET'S GET TO IT! ;D

The Solution with no crashing - try opening your console and write in there this : "changelevel freddysnoevents" it might work! or...go launch gm_construct and type ''changlelevel freddysnoevents''.
if it doesnt works for you try to restart your gmod and type it again!
if it still doesnt works try uninstalling some addons, you'll never know what can a single addon do to your every map in your gmod!
if the map still doesnt works you have a small ROAM space, try getting it almost empty and uninstall some useless games/files/etc to get some more space.
still doesnt works? try updating your graphic card.
still not working? buy a new graphic card.

if i helped you please leave a comment down bellow!

Good Bye! Hope i helped!
