I'm willing to work on fixing this, but I'd appreciate some direction. I poked around the repo briefly, but I couldn't find the relevant code. I'm assuming based on the error message that objdiff is trying to open a prompt with a default directory that doesn't exist.

EDIT: Confirmed also broken on v3.0.0-beta.8 although the error message is slightly different:
