Minecraft 1.19.2 | Forge 43.3.0 | Couldn't place player in world

[srimp]

Hello, I am getting an error when trying to load into a personal modpack of mine. It's been giving this error ever since I started working on adding mods again, and I don't know what's causing it. I don't have a crash report since it is merely me getting kicked from my singleplayer world but I do have the error from the logs. I can provide the full log and debug.log on mclogs or pastebin if required.
