4K Criterion "Alice Doesn't Live Here Anymore" Problems

[ActorCam]

I can rip the new Criterion 4K "Alice Doesn't Live Here Anymore" to my iMac hard drive, but when I try to load the BDMV file from the rip back into MakeMKV to create MKV files, the load fails and I'm back at the main MakeMKV menu with no error message. Is there a new encryption algorithm MakeMKV can't handle yet? Or some other reason why this is failing? It's the first time I've had trouble opening a BDMV file from a 4K disc I was able to rip.
