Hello,

Where is this log from? Does it come from the nRF Connect for Desktop -> "Programmer" application? If so, can you please try to recover your nRF first? Try the command:

"nrfutil device recover" in a command line terminal. Note that nrfutil needs to be in your path.

Let me know if that doesn't help, and let me know where this log comes from.

Best regards,

Edvin
