Scaler 3.3 crashes Cubase 15 pro

Hi, each time I add a Scaler 3.3 to a Cubase project it crashes Cubase.

Previous version of Scaler 3.x was working well. Scaler 3.3 standalone works well.

Windows 11 up-to-date. Cubase Pro 15 up-to-date. Works perfectly if I don’t add Scaler 3.3

Antelope Zen Quadro up-to-date.

Any help would be greatly appreciated.

Thanks in advance.Best regards, erix
