R^3 is crashing constantly and I can't figure out why

[lingusbingus]

It's what the title says.
I have never seen this issue in any online game I have played before. It's just fatal error after fatal error, and it has gotten to the point where the game is virtually unplayable now.

That is, in the sense of the game won't fucking open anymore. Language won't load, hangs at startup, user data won't load, halfway through a fucking song and it'll jitter a bit so I miss like 10 notes and then it fatal errors and won't save scores and won't load songs.

I wonder if anyone else has this problem, because I can't find a solution. It's ridiculous, and if anyone, literally anyone has a solution, I'm all ears.
