Prints no longer work, abort with "crash detected" message ( video inside )

Hello,

after using my Prusa i3 for a year now i suddenly experience a weird behaviour, signalling "crash detected" when printing projects.

Everything i changed recently was adding a .6 nozzle and updating the firmware to the most recent version.

I did successful prints with this setup, without any issues after these changes, so i can really not explain what happened.

I use Octoprint and Prusaslicer in my printing-chain.

Here a quick video, you clearly see something is really wrong:

// edit video link here, embed function did not work for some reason

What i see is that the printer does not even extract any filament in this stage ( temperature are okay as the display shows me ),

and the initial filament load worked and extracted normally.

Any hint at which point to search for a problem?

Thank you very much !
