Update: download Java 16 to fix this. download it here: https://adoptopenjdk.net/?variant=openjdk16&jvmVariant=hotspot 

I cannot launch any servers for 21w19a, probably due to the upgrade to Java 16. This may only be something I need to do on my side to fix but I am unsure how to fix it. here is what pops up when I try to launch a server using a start.bat file or just the server.jar file. If I try to launch a fresh server, it wont even generate the needed files such as EULA or Properties. If this is faxable on my side, please tell me how to do it. (I assume I need to download Java 16?)
