MC-227862Server 1.17 won't start | JNI error
I downloaded the minecraft server version 1.17, because I wanted to set one up for me and my friends. How ever when I started it I get these error messages in cmd:
D:\...\...>java -Xmx4096M -Xms1024M -jar server.jar nogui
Error: A JNI error has occurred, please check your installation and try again

The path is correct and I tried it with my older java version and I tried launching it with a freshly downloaded java version. My old servers (1.16) still start just fine.
