As the title says. The later half of the disk fails to rip, I can get around ~90% of the way to ripping file one of the 4K BR before it fails with a popup message. Attempting to play the file in a player results in no video and a runtime of the full disk. Not sure on specifics here, but figured it' worth posting. (this is for 4K disks rip specifically)

You post in the Bluray Disk area, but say your problem is with the 4K rip?

There are numerous reports of the 4k version needing to be "cleaned" to rip properly.
