Gmod crashes when creating a server

I just tried to create a server on gmod and when “Initializing game data” appears, it instantly closes and says hl2.exe has stopped responding.

I’ve last time I’ve played gmod was like 2-3 days ago.
I deleted and re-installed gmod
I’ve googled it.

Still nothing please help!
