Realms Configuration Crashes Game 1.17

I uploaded a saved world to realms and ever since then when I press configure realm to change my world it says saving world and crashes. I can't play or change it to my original world and I would really like to.  Also switching Optifine to Vanilla didn't do anything. Someone help, please. 

I also have my crash report here: https://paste.ubuntu.com/p/dVHxbSVDk6/
