Unable to Generate Keys using nrfutil

Question

I'm trying to follow this how to and unfortunately cannot make it past step one.

https://devzone.nordicsemi.com/guides/short-range-guides/b/software-development-kit/posts/getting-started-with-nordics-secure-dfu-bootloadery

I'm using Python 3.9.7, I have it set as a path variable

I have GCC compiler toolchain for ARM installed along with GNU Make

Any help would be appreciated.

It is always throwing this error

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
