Zen 2 Processors - crash if setting another track to be default
I tried various versions from latest 35.0.0 back to v26, all have the same issue on the new Zen 2 processors (3900x in my case).
Setting another track (audio or subtitle) to be a new default, then hitting Start Multiplexing kills MKVToolNIX Gui, and it refuses to start until you delete the job file in jobqueue folder. After that it starts up again.
Tried it with multiple movies, same thing with all of them.
Open mkvtoolnix, and drag over the movie... you get this --> https://imgur.com/a/7y1YLHT Change the defaults --> https://imgur.com/a/yNpIwlF Click Start, mxvtoolnix closes down and wont start back up until the Jobqueue file is deleted. The queue file that needs to be deleted (with .mtxcfg extension) is attached.
PS - Copying same files to an intel machine, no issues performing the exact task. Similar issue has happened with other applications, notably the game Destiny 2, in case that helps guide in the right direction - https://hothardware.com/news/amd-ryzen-3000-zen-2-destiny-2-bungie-crash
