[USB-TC gives intermittent error in LabVIEW]

Thanks for the suggestions, @Fausto. I didn't have other modules or other systems to swap with. We tried using a different USB port and that seems to be working so far. The advice to keep it from EMS sources is helpful, too.

[USB-TC gives intermittent error in LabVIEW]

I made a LabVIEW 2017 application that reads 3 channels of temperature data from a USB-TC using the ULx functions. It has been working well for several months, but now intermittently gives wildly inaccurate values and an error from the ULx Read vi of Error Code -10001 "...thermocouple input channel returned an invalid temperature ...". Sometimes it reads correctly, sometimes not as the application runs, no changes made by the user. It can affect one, two or all three channels. No loose connections could be found. Any ideas on troubleshooting this issue?
