Is ther a know issue with Windows 11 ?

[NoSoup4you2]

I am wondering if there is a known issue using the MediaToolKit with windows 11 ? I have a Custom App that uses the toolkit
to trim a file at end and start and convert it from mp4 to an mkv file. In Windows 10 my code work just fine but last week i moved to Win 11 and now it fails. Instead of a converted file I get a 2KB which is some meta data only..

Below is the code i use to to the basic conversion / trim. Interesting if i do a conversion / reencode it works fine..
Also to note if i move the same code back to a windows 10 vm it works like a charm

Dim cmd As String = $"-i ""{inputFilePath}"" -ss {trimStart.ToString} -c copy " &
                                       $"-t {outputDuration.ToString} ""{outputFilePath}"""
                   engine.CustomCommand(cmd)
