Synthesizer V Studio Pro crasches loading Natalie Voice

Hi,

I just bought Synthesizer V Studio Pro V (28.08.2023) bundle with ai voice Natalie.
Synthesizer V Studio Pro seems to work fine, I can write notes and they are played with sound.

When I load Natalie voice, Synthesizer V Studio Pro crashes - Standalone and Vst also. Vst crashes Studio One DAW. Standalone crashes with internal Soundcard and with external audio interface when loading Natalie.

I have a PC:
Intel(R) Xeon(R) CPU X5355 @ 2.66GHz (2 Processors).
32 GB Ram,
USB Audio IInterface Scarlett 18i8 second generation.

Windows 10 Pro Systembuild 19042.631
Version 20H2
Windows Feature Experience Pack 120.2212.31.0

64-Bit- operation system,

Yamaha Vocaloid with latest AI-Voices is working with no Problems.

Can you help?

Best Regards
Inke
