"Playback Error" Conversion failed. The transcoder exited due to an error

[johnm_ColaSC]

There are several other threads dealing with the Transcoder that all have the same solution for Windows 10. Here is one of the ones I have posted on in the last day, Conversion Failed. Transcoder Exited due to an error - #4 by johnm_ColaSC.

Without logs I can only assume you are experiencing an issue with the Transcoder that is caused by a recent Windows 10 Update. Microsoft has released two patches since the update that caused the problem.

Please verify you have the following Windows Updates installed:
July 10, 2018 - KB4338819 (OS Build 17134.165) - which introduced the issue

July 16, 2018 - KB4345421 (OS Build 17134.167) - First fix

July 24, 2018 - KB4340917 (OS Build 17134.191) - Second update Microsoft released fixing issues
