Thank you for the suggestion, but this also failed to resolve the issue.

https://pastebin.com/ZjNDHQjh I cannot start a world without this error occurring. I have been trying to solve this problem all day. I've wiped everything, uninstalled all mods, verified file integrity, installed a fresh copy, ran it as an administrator, and tried previous betas (only as far back as 20.0) but nothing has worked at all. I'm not trying to join a server. I'm attempting to play single player. If anyone knows any further procedures to fix this, please let me know.
