<p>The problem is that the <b>stand-alone</b> installation of QGS
3.10 (64 bit at least) doesn't set the PYTHONPATH environment
variable, so the python interpreter can't find the module.
However, the "<b>network installation</b>" of the same QGIS
version do set the variable. And that version works without a
hitch</p>
<p>If you add a custom variable <b>PYTHONPATH</b> with value <b>C:\PROGRA~1\QGIS3~1.10\apps\Python37;C:\PROGRA~1\QGIS3~1.10\apps\Python37\Scripts
</b>to the stand-alone version of QGIS 3.10 (and restart the
program) the "polygonize (raster to vector)" works in this version
too.</p>
<p>So I suspect we might have a packaging problem with with the
stand-alone installation</p>
