Are you able to notice any signals on the I2C lines when you probe them?

no, nothing on the I2C lines. That is why at first I thought, that the I2C transceiver is damaged. But I changed the chip and disconnected everything but the pull-ups and this did not help.
The strange thing is that the notification LED stays on for about 10s, when I try to transmit something.
