code is here , it always the same development going on
I have too much going on to go hunt for your code in other topics, sorry.
Please have a look at cura.log in your configuration folder. It will tell you if there's a (Pyhton-)error in your code. The file is probably fairly large. You can delete it and Cura will create a new one. Then start Cura and the log will tell you what is going wrong.
Specifically the bit " -> List[PrinterOutputDevice] " is called "type hinting"; it tells Python what sort of data to expect. It is optional (but recommended). It could be that Python is having an issue understanding what "PrinterOutputDevice" is; are you importing it?
from cura.PrinterOutputDevice import PrinterOutputDevice
yes of course is standard in pluging import statements i have
from cura.PrinterOutputDevice import PrinterOutputDevice
the log says that :

Without the rest of the code or an understanding of what your plugin does, there is no way we can tell you if that code is required.
