Did you build the extension yourself or did you use the release binary?

How did you launch Ghidra? Is this using it headless from the command-line?

[BonusPlay]

Built myself (latest commit is newer than release binary), ghidra ran with UI.

[cblichmann]

This is odd, it looks like the Gradle build did not add the Protobuf dependency correctly.

I'll try to debug this issue a bit, as this might be caused by nix-related build stuff. I can see following classes in the ghidra-binexport.jar, but have no clue why it isn't working...
