So I've been trying for the past several hours to create a singleplayer world with forge, but each time I create the world it just says "Saving world" and freezes. I was originally doing this in 1.16.5 because that is the only version the mod I want to use has available, but decided to try with the latest versions 1.18.2 and 1.19 too and got the same results. I don't have any mods in the mods folder, it is completely empty. I've reinstalled each forge version multiple times. I have restarted my computer, I saw some older suggestions saying log in and out of the launcher, I've done that. Vanilla minecraft works fine, both singleplayer and multiplayer. There is no crash report, I have to forcefully quit the game each time. I've been getting a mix of error code 143 and 9. I'm not sure what happened to make everything seemingly break, it was working fine a few months prior and I haven't changed a thing. I've tried allocating more RAM too.

This is the debug log, it's shortened because it's just these three lines over and over and over again to the point pastebin won't take it:

Thank you!

Change your max fps to be non-zero in the video settings or your options.txt
