Hello,
Thanks for reporting

Is your image shareable for investigation purpose or is it not?
It will be hard to investigate without more details

I don't think it's related with image at all but just with ./out/ folder not existing (no crash after creating).

Also had similar crash when it tried to extract from corrupted cluster where was binary folder name.
