Could not initialize class libdwarf.LibdwarfLibrary

[xobs]

Adding an issue here in case anyone else runs into the same issue.

I installed ghidra2dwarf by extracting the release zipfile and adding the resulting ghidra2dwarf directory to the Script Manager. However, when I run the script, Python gives me an error that says it cannot load the library:

Update: After removing and re-adding the script, I get a different error now. It seems like there is something precompiled that does not work on aarch64:

I've tried recompiling libdwarf.dylib as arm64 and rebuilding libdwarf.jar but that doesn't seem to make any difference.

Note that as part of this change I had to change the target version from 1.7 to 1.8 in order to get it to build.

I'm unable to get this working on x86-64 under Windows as well:
