I installed the server and it installed fine, whe I try to open it it gives me this error. The only thing I changed from the original command "java -Xmx8G -Xms8G -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=0 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -XX:+UseG1GC -jar forge-1.16.5-36.2.8.jar nogui" was the forge version because when I downloaded the files the forge version included was difrenet. Many thanks

I installed Version 36.2.34 and it's working fine. https://files.minecraftforge.net/net/minecraftforge/forge/index_1.16.5.html 36.2.20 that was included with this pack is not working.

Thanks @Shadowgar.

Using forge 1.16.5-36.2.34 fixed the issue.
