Searching for 4 hrs I found a solution to fix this.
If you have another source game installed example hl2 css etc go into its directory
copy hl2.exe from there and paste it in your garrysmod folder overwriting the orginal exe
Then right click it make a shortcut. In the target box type
-game garrysmod -autoconfig -nocrashdialog
save it and run the shortcut it should work now.
