WIO Terminal drops USB connection regularly

I just bought a WIO Terminal and I can’t keep it connected during development. Once code is uploaded, it may run for a while just fine, but after a minor code change, Win10 complains that the USB device is unrecognized. Sometimes it just drops while it is running. I have to restart the PC. I have all virus and malware programs disabled, as this fixed the same issue when I was developing on my ESP32 boards. Using PlatformIO, if that makes a difference.

This has become extremely annoying, and I have a large project to work on. Anyone else having similar issues?
