@pt615
According to protobuf releases page:
At v3.18.0-rc2, protobuf drops support for python 2.7 and 3.5 (View here under 'Python' section)

In order to work with this package, you should install an earlier version of protobuf, such 3.17.3:
pip install protobuf==3.17.3 --upgrade -q
NOTE: The --upgrade flag can be used for both downgrade or upgrade. (Reference)

This worked for me, hope it will fix your problem too.

try the docker image please

https://github.com/FSecureLABS/drozer/tree/develop/docker

The commands you put up worked for me, I hard coded the path for java in the drozer config py file.
"\drozer\src\drozer\configuration.py"

path = system.which(name)
changed to;
path = 'C:\Program Files\Java\jdk-19\bin\javac.exe'

#is the required exe available on the PATH?
if path == None and cls.get("executables", name) == None:
path = 'C:\Program Files\Java\jdk-19\bin\javac.exe'

Hope that helps, I have had a lot of problems as well, so I am not sure if that one was the fix.
Good luck.

closing this issue

the docker image has been well received and works pretty flawlessly
