Crash report

I was playing mc java w/ forge 1.20.1 and mods worldedit 1.20.1, after a couple minutes of building my sky base, i get disconnected. the error code is -1. i tried again and got kicked after just a couple seconds of joining. i have done a bit of research and it means some part of my world is corrupted, but minecraft doesnt know where. it could be unfixable in some cases. i dont know if its to do with worldedit mod, a creepypasta (who knows maybe real) or a mob unrendered properly (it cant be a player, im on singleplayer) i was pretty high up in the sky and all that was rendering is some jungle trees, and for some reason it looked like there was a gold block down near my other build, even though i did not drop a gold block down. i dont know if it was for sure a gold block, i could just see spinning yellow 200 blocks down (i used /up 200) it was before i got kicked again, a couple seconds after seeing it. both the times, there was some lag spike before it crashed. the world was on originally vanilla 1.20.1 but as you know i used forge. i have created a pastebin with logs because of character limit:
