Everytime I try to join a world I get exit code -1.

I was attempting to go back to my practice world so I could continue training my skills. When I loaded up everything seemed normal I went inside of 1.16.3 and went to my world. Then when I clicked to join it said essentially said preparing to load. I recently bought the game and thought that was normal. After a few moments, it said world saving then I was sent back to the launcher. After it fully loaded I saw that it said exit code: -1. So I searched on the web and whenever I searched -1 it would show long number strings. So when I finally got to this site I had hope but I couldn't find anybody with the same issue. Thank you for your assistance and have a great.
