It looks like the python code can't open and connect to the UART port of the nRF52. We also have this issue some time with NRFConnect. We currently don't have a solution for this except unplug the board and plug it back. The reason could be because of the Segger interface chip.

I use NRF52 board flashed with connectivity firmware.

I connect to the computer via ssh, so i can only give you logs from nrfutil:

Could you take a screenshot when the issue happens ? Which device/board you used as the backend for nrfutil ?
