Hi Andrea, I updated QGIS in the meantime from 3.34.6 to 3.34.7-2, the problem occurred in both versions.
And yes, there was at least one, probably two, Windows updates during the time I had this problem. I used the Windows standalone .msi installer, and after the installation was complete I removed 3.34.6. I tried if the problem persists when I use a bare bone minimal profile, with no effect on the issue. So maybe its possible that the problem is caused by some change in the windows .zip-handling? Honestly, I have no idea where to investigate....

Hi Simon, you wrote that the issue occurs "since several weeks": did you use the very same QGIS 3.34.7 version even before several weeks ago when the issue didn't occur? Have the Operative System been updated? Which installer did you use to install QGIS, the OSGeo4W network installer osgeo4w-setup.exe or the OSGeo4W stand-alone all-in-one installer QGIS-OSGeo4W-3.34.7-2.msi or another one? Have you tried if the issue occurs also using a new QGIS user profile?
