Ok I found both (How could I have missed it ;-) ). I recorded a viewing session of about 20 min., until and past the moment the screen freezes. I wanted to select only the last few minutes for you, but I cannot open/play the MP4 outside of the Quest. I can get it from the Quest (Internal Storage/Oculus/Videoshots), but cannot do anything with it. I can watch them with the Quest (Gallery or Skybox). I messed up the file, so that one is lost, but if it is helpful for you, I can record and provide you with a new full ~20 min recording.
