Cannot Change from 48000 to 41000

I just purchased Dorico 3, an upgrade from Dorico 2, and I cannot choose 44.1k for NotePerformer.

I am on Windows 10.

What should I try to do?

Where do you try to change it, under Edit > Device Setup?
In the list of sample rates is only 48000Hz?
What driver are you using, the Generic Low Latency Driver?

Yes. I have gone through device setup and it is the generic low latency kind.

Could you please do Help > Create Diagnostic Report
That creates a zip file on your desktop, please attach here in the forum.

It says that the diagnostic file is too large.

You can email it to u dot stoermer at steinberg dot de.
