I found out the issue with my software. sdkretschek are you by chance getting a Coretelephony Trace File Error? If so, you need to clear this out before MakeMKV will work.

I'm having the same issue, and I've never had an issue before. I also do not have anti-virus. Please help!

I, too, played the Redbox Blu-ray alongside 428 and it lined up perfectly.
