Problem DW20 1.16, can't load my singleplayer world

[Icemanap]

So, DW20 has not been entirely stable for me in general. It freezes sometimes, but otherwise is fine. But while i was trying to create a wheat farm with create, suddenly i could not interact with the world. I could walk around and access my inventory, but broken blocks would not drop. So since i thought it was another weird freeze, i closed the game and tried to reopen it. But when try to load my single player world it reads world data, but gets stuck at 100% when loading the world. I have tried downgrading to earlier versions (which did not work because there was some error in mods and forge). I have also tried deleting the modpack (after backing up my world) and redownloading it. What should i do? Below i have the minecraft game output before the loading gets stuck:

And after this it got stuck for 20 mins and i decided to close the game. This exact output is repeated every time i load the world
Update: I went back to an older back up of the world. Seems to work fine for now
Update on Update. Same thing again, exactly happened when i was near my create farm
