can't load the synthesizer.

When I switch to Sonata Nural Voices add-on I get an error that it can't load the synthesizer. The voice manager works and lets me demo and download voices. I also installed one from a file.

My NVDA version is 2024.2 if that helps and it is an installed copy running on Win10 Ltsc2021 x64 build 19044.4529.

I uninstalled both Piper and Sonata and deleted the Sonata and Piper folders from %appdata% then reinstalled only Sonata and installed one voice in it.

The previous Piper Nural Voices add-on was working.
