So I downloaded the version 1.12 but the mods I had didn't work on the version so I downloaded the 1.12.2 but in the minecraft versions it didn't appear. I tried everything to delete the 1.12 version but nothing helped and I couldn't get a 1.12.2 version in my minecraft launcher. And according to Google nobody had a problem like me before or I simply couldn't find a solution.
