None of my modpacks work, except for Vanilla

Hi! So, I've played with the technic launcher for years, and recently, it's stopped working. It loads the files just fine, and when minecraft starts up, all it shows is a white screen before crashing shortly after that. I don't know if I'm supposed to give any information or not, this is honestly the first time I've ever had to report an issue.

That's the information of the most recent crash

Thanks!
