Android won't install anymore after resetting of my Jolla tablet

Hi,

I’m one of the few people who received the Jolla Tablet and I just wanted to reuse it.
Unfortunately it won’t install the Androiud Support anymore.
I’ve just reset the device and went trough all the updates up to 3.4.0.24.
now there is popping up Android support couldn’t be installed. (roughly translated)

Any clue what I can do? Is this a known issue?
