After I updated to 1.17, one of my single player worlds is having a glitch when I enter the overworld and nether. For example, if I start in the overworld everything is fine, but then when I enter the nether, only a few chunks will load in; another problem is that I cannot pickup items. Everything is fine if I just exit out of the world and then go back in, but it happens both ways, from the overworld to the nether and vice versa. Additionally, this only happens in my main world that I play; I tried it out on a creative testing world and everything was fine. I tried making a backup of my world (the one that's having issues), but nothing changed; I also optimized the world but nothing changed. I'm not sure why this is happening. I've attached a few screenshots below
