Trying to load a saved game, but Gmod crashes

I’m working on a save on Gm_Flatgrass where I’m building a fort, but since yesterday, everytime I try to load it, the “hl2.exe has stopped working” error pops up just as it’s finishing loading. Please help, I don’t wanna have to build it over again.

i have a similar problem. sadly i do not know how to fix it.

Which is why you should use the advanced duplicator :v:
