I decided to learn how to make mods for minecraft. I follow this tutorial - https://codakid.com/guide-to-minecraft-modding-with-java/. I have this problem that when I hit run, the minecraft window pops out. The forge starts loading, and then it closes. I havent written any code so far. So there must be sth wrong with my setup. Can anyone help me? crash-2020-11-04_11.03.33-client.txt
