All 4K movies and tv shows not converting

[Bulletmagnet24]

I have been having this issue since the last update where any and all 4k movies or TV shows are not converting, they all go through the process of Folder process or by selecting the drive to convert and once finished, there is no sound or picture and after several minutes, a message pops up "cannot play"

I am trying to convert all my physical content to digital for my media player. It work a while back and hasn't for a while.

On the other hand, all DVD and blurays bot movies and TV series are converting and the playback is amazing

Is this an issue, if this is will there be an update to correct this error
