Minecraft Crash.

[batcg]

Hey everyone. I was thinking about play minecraft with mods long ago. So now, after 3 years of not playing this game, so i installed some mods, libraries and decided to play. After 30 minutes of fixing bugs of curseforge (I set 1.12.2 in mods search and it get me 1.13 for some reason) i finally launched game. And its crashed. Anyone can help?
Game: 1.12.2

1920x1080
With optifine.

 

PC:
R5 3600
1660 6gb
