Description
Raster -> Conversion -> Polygonize (raster to vector).
This process was taking a very long time and I wanted to stop it.
I clicked the progress bar in the status bar below the main map view and tried clicking the red "X", but it does nothing.
Exit QGIS (CTRL+Q) prompts if I want to attempt to cancel the active task, but does not succeed at this.
My final solution was to terminate the QGIS process manually via Windows Task Manager.

Actually GDAL algorithms (as well as SAGA and GRASS) can not be cancelled, see #18600. Confusion comes from the fact that in QGIS task manager we still have a cancel button for them. Here is PR to fix this https://github.com/qgis/QGIS/pull/9026.
Closing this, as implementing cancellation support is a feature request and we already have #20060 for it.
