While opening my minecraft world, I have encountered an unbearable lag that’s caused by high usage of memory and disk. It started about 2 to 3 months ago, and became more frequent in the last month. I haven’t installed any type of addon or resource pack on this world (cheats disabled), but I have been playing on it for quite a while.
I have attached some screenshots that might help.
Thank you and have a great day!
