Gmod stuck at loading screen

So, pretty much what the title says, Garry’s mod doesn’t load past the first part with just “Loading…” in the bottom right corner. I don’t see the blue loading bar pop up or anything. It’s been going on for months, I was able to run it perfectly well before that, and I’ve completely reinstalled everything multiple times. It’s not working. Any help?

DId you try reinstalling steam as a whole?

Yes, that didn’t help.
