Problem FL Studio and Reaper ( No! Windows 11 connect problem)

Hello! I write through a translator.
When you connect a Cortex USB as an interface to both DAWs, the problem begins. At first 5 seconds sound is good. Then the crackling starts and Fl Studio freezes. Exactly the same problem in Reaper. And also Windows freezes next, and you have to do a reboot.

New clarification! FL Studio and Reaper have nothing to do with it! The problem is that Cortex does not work as an external sound card. In the Windows settings, I select Cortex for audio playback. I turn on YouTube, for example, or any other sound - trsec, the system freezes!
Please help me solve the problem!

Hi @gsm3694 and welcome to the community! I would suggest adjusting your sample size and or rate first, if that doesn’t work, try setting the driver control to safe mode. Worst case, email support@neuraldsp.com and they will get you sorted quickly.
