***I was able to fix it. It was a bug where my fps cap was set to 0 fps (if ypu use lunar and you set the fps cap to "v-sync' when u load into normal mc it sets ur fps cap to 0*** NOTE: This bug affects versions 1.15.0 - 1.17.1 but i couldnt put that in the affected versions section When ever I load into a world after the colored chunk map it says "joining world" then "saving world and gets stuck on that until I restart my pc or task-manager Minecraft. for server and realms after "connection to _______ (realm/server)" it says "joining world" then "saving world" and just like if I join a single-player world it gets stuck and I have to restart my pc or task-manager Minecraft.
