1. Uninstall Voicemeeter.
2. REBOOT.
3. Install Voicemeeter (I like Potato, but you might still like Banana).
4. REBOOT.
5. Open all VB Audio control panel app's and set your desired sample rates.
6. Open the Windows Sound Control panel (the old, legacy one) and set your preferred sample rates on all recording and playback devices associated with Voicemeeter.
7. Start Voicemeeter, your old settings should be preserved.
...and soldier on with the scars of yet another Windows update.
I do like some of the features of 1903. No pain, no gain, I guess

73!
