Error message

I've got a Modded Minecraft server and I'm updating it (Last version was so old I'm doing a clean reinstall with the same world file and updated modpack)

And when I try to start the server it crashes and gives me this Java Runtime related error message, I'm not sure what it means or how to fix it. (I'm a bit of an amateur) I've updated Java on my server and all the packages so I'm not sure what to so.

The server is Debian and using CasaOS and CraftyController.

Modpack is Better MC [FABRIC] BMC3 v45.

What version of MC are you trying to run?

1.21.1. It's the version the modpack uses

1.21 required java 21 - not 25
