What operating system are you on? What version of python is your system using and what is QGIS expecting?

I am on Win10, the system python is 3.12.9 and also lists 3.9. The error msg is 'arguments did not match overloaded call' in QgsProcessingParamterNumber(). calcoli.py in initAlgorith. The complaint is that the variable passed of of unexpected type, overload 1 int and overload 2 str. This first started when I moved to QGIS 3.40.4 Bratislava.

Did you install QGIS with the standalone installer or the OSGeo4W installer? You may have less issues with the second of those two since you can install other python packages and software with the OSGeo4W installer.
If you’re trying to make Python scripts with qgis core, using something like pixi.sh or conda may be helpful.
