Same for me, 1.12.2 works fine but 1.20.1s forges just don't open and i wanted to play with my friend so i would need to install a server. If anybody has a server instalation pls send it to me. Btw a simple fix for this if you don't care for server hosting is installing it through curse forges launcher then forge works just fine but i need this server install
