My world just doesn't open, it keeps saying that it has no memory, but I have 1 TB on the hard drive. The funny thing is that it only happens when I am at a considerable distance from my respawn

This started from version 1.16 and higher. I don't know what to do, I'm desperate because I'm a content creator and I wanted to continue using my world. I tried to install an older version but it didn't work, I tried to restore my hard drive and it also didn't work...
