How to reproduce the bug

unrpa images.rpa
Extracting files from images.rpa.
Auto-detection of the version for this archived failed—it is likely this archive is a version not supported. Try updating unrpa, or submitting a request for support at https://github.com/Lattyware/unrpa/issues/new?template=new-archive-version.mdHeader: “��~�E�;���R”
You can try using --force to force a specific version rather than relying on auto-detection.

unrpa images.rpi
Extracting files from images.rpi.
There was an error while trying to extract a file from the archive.
If you wish to try and extract as much from the archive as possible, please use --continue-on-error.
