Hi @NicoF!
There a some warnings and errors. I found these in your log file (and there are more):

SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
So, you need a more powerful power supply.
Check your Klipper installation.
Disable the astroprint plugin.
