Quick question; I assume I cannot use the mods I removed on any world, right? Or do they just cause issues while creating the world?

Did that, works fine, but is extremely laggy. It was like this before I updated it though, so it's probably something with my computer

Did I do it correctly https://paste.ee/p/X8x0j

Ok little update. I assumed that the world file was already created, so I entered the game to check, and I was right. I entered the new world and spawned on a Deep Dark biome lol. Not five minutes in and the game froze, I waited for around 8 minutes to see if it picked itself back up, but nothing happened. I tried Alt + F4 out of the game, and after another error pop-up I was booted out of the game. The Minecraft launcher came up and showed me this error code: -805306369

I tried out what you said, and there was a bit of progress. I was able to proceed into the world creation menu, but when I tried to actually create the world, the game got stuck on a loading screen and crashed after approximately 3 minutes of loading. I'm not sure if something changed in the crashlog, I barely understand any of it for starters, but I'll quote it below just in case

I'd like to report an issue that happened to me while playing in Forge 1.20.4. Before installing 1.20.4 I played in Forge 1.20.2, I had my modded world and I enjoyed it, but i decided to update to 1.20.4 due to it having a lot more mods I wanted to try out. I installed 1.20.4, then the mods, and after some mod troubleshooting, I was ready to play. When I entered the World menu, I decide to erase my old world, since it had mods that were made for 1.20.2, and I wouldn't be able to play in it anyways, but after it got deleted, the game crashed. I assumed it was a little misfortune, and opened the launcher a pair of times after that, and every time I tried to create a new world, it'd crash. Could anyone please help me? I assume everything will be fixed by deleting my old world's file directly from the game's files, but hell if I know where to find where the worlds are stored. I'll copy the crash report below in case it's needed. Oh, and one last thing, this is the first time I post here, so I'm sorry if I broke any rules or if the way this is written is inconvenient
