Hello, Welcome to Microsoft Q&A,
Based on my tests, PIX version 2310.30 and newer releases cannot connect to HoloLens and the version 2305.10 is fully functional. Try using 127.0.0.1 or UsbNcm IP to establish a connection. To find your UsbNcm IP, please refer to https://learn.microsoft.com/en-us/windows/mixed-reality/develop/advanced-concepts/using-the-windows-device-portal - connecting-over-usb.
