Me and a friend of mine tried to install a forge-server with the minecraft version 1.16.4 (java 8). For us it was not possible to run the server (more information in the screenshot attached).
Furthermore i cant run the client version of forge 1.16.4 on my pc (already tried to reinstall multiple times).
