Forge 1.16.5 extremely laggy, takes an hour to load up, missing blocks

[rwuby]

I just got my 1.16.5 Exit Code 1 solved and it's loading up Minecraft just like before but not it takes over an hour just to get into a world between hitting the play button and the launcher and actually spawning into the world. It's also extremely laggy though, and when I turn on shaders, some blocks are invisible even though I can still interact with them.

Here's the debug log (I apologize in advance, It's EXTREMELY long); https://paste.gg/p/anonymous/fca91ccfd35c472da2d68e530c78e4c1
