Audio Drop outs Cubase 15 pro

Hi

I am searching for a solution for a problem since I bought Cubase 15 pro. I own the following setup;

Windows 11 pro, Nvidea GeForce gtx 1660 super, RAM 64 GB, i9 10900 intel chip, Prosonus studio 18/24c

After I install Cubase 15 pro my projects always got sound dropouts.

I disable power throttling doesn’t work,

Installed studio driver NVidea driver

Latency monitor gives no problem

Stop hyper treating.

Thanks
