Noteperformer Timeout on Dorico 4.2 - Windows

I was in contact via private message with AragornK and it turned out to be a graphics driver problem. The vst2xscanner would not work, because it was endlessly hanging while trying to unload the NotePerformer.dll.
So the FreeLibrary Win API function was hanging while making a call into the graphics driver atio6axx.dll from AMD and a change of that driver cleared everything. Here is what AragornK wrote me:
“For your information AMD has two main streams for their graphics drivers: Recommended, and Recommended + Optional. I was running the Recommended + Optional stream (version 22.8.2) and downgrading to just Recommended (version 22.5.1) was what resolved the VST scanner issue.”
