Cannot set security manager! Are you on Java 18+ and have not enabled support for it?
Because of this, you may be susceptible to some exploits!
Either deal with it or allow it using the -Djava.security.manager=allow parameter.

I have found a forum post that discusses this issue in relation to your OS. You may find this link useful. I hope this solves your issue.

Hey @TechComet, thanks for the report. I believe to make the CLI work correctly we'll have to separate the GUI from the core. Essentially the CLI will need to preform actions without relying on the GUI. There's no ETA for this yet but I'll work on solving this. Sorry about that issue!
@Bl3nd Thanks for the solution! Hopefully that will work in the mean time.

I was hitting this issue as well. The link above by @Bl3nd was very useful and led me to the simple fix:
Looks like I had a headless version installed, installing the regular one and bytecode-viewer starts right up.
