Avidemux Crashes When Trying To Play Mkv With FFMpeg Audio (I Think)

[LouieChuckyMerry]

Hello, and thanks in advance for any help. Also, if I posted this in the wrong place then please move it as necessary (and thanks).

For years I've happily used MeGUI to shrivel my DVDs and Blu-rays to .mkv files with 10-bit x264 video and Nero .m4a audio. Also, I've used Avidemux regularly to cut clips from these encodes without issue. Very recently I started using Pazera Free Audio Extractor to downmix the audios, as I find it much simpler for batch processing. Unfortunately, this new form of audio causes Avidemux to crash, but only if I try to play the .mkv; that is, I can load the .mkv in Avidemux, I can navigate forward-backward in the video, and I can save a section of the .mkv without issue, but if I try to actually play the file Avidemux crashes with the error message "ExceptionFilter. The application has encountered a fatal problem. The current editing has been saved and will be reloaded at next start." Clicking on "Show Details..." results in:

which to me is a foreign language. Please, does anybody know what this means and if there's a way to rectify it? I tried to register on the Avidemux forum but wasn't allowed to. Thanks again for any help .

Edit: Apologies for the emoticons in the above quote, not sure how to fix that.

EditEdit: In case someone finds it helpful I found a workaround, if not an actual solution, with help from someone at Doom9. Here's a link.
