Guys, I'm trying to see what I did wrong, but there's no use you need to help me please.

I've had this problem since yesterday and since yesterday I tried to solve it and I came here to see if one of you can help me with this,
I tried for mods in the game and this error and others appeared but even if I try to play the game without mods it still remains the same. Am I doing something wrong?

if the image is not showing here is the error:https://prntscr.com/s22na1
