Vienna Instruments Pro and Komplete Kontrol

I’m having an issue with Vienna Instruments Pro and Komplete Kontrol. When I export a track in Cubase 10.5 with a piano library on my VEP server, the result is all garbled. I’ve tried setting my latency higher, enabling/disabling Asio Guard, to no avail.It works fine if I use VEP outside of Komplete Kontrol. any idaes?
