Found it was alway the aksoundengine.dll that crashed (check eventviewer on a windows PC)
Reüplacing it with an older version made it better but still crash at second game.
Next I entered the registry and found in user-settings of MTGA "invalid-settings" for volume settings.
I simply deleted these entries and was able to play 1 game but in the second game it crashed again.
The only solutions so far is really switching the language to english...
