Debugging "error: board failed verification"

Hello,

I’m having a problem of receiving the error message: “error: board failed verification” while trying to Flash Device using the web IDE on computers in my lab. I’m not sure how to debug this and would appreciate help. Connect Device and Run Synthesis both appear to work fine.

This currently affects all the Windows 11 computers in my teaching lab. They’re using Chrome (ver 146.0.7680.178) and I have also tried Edge (ver 146.0.3856.97). I tested that all of these worked last Thursday (Apr 2) before class, and then on Friday (Apr 3) during class only about half worked. Now (Apr 6) none do. I suspect this is due to an automatic update to either Windows or Chrome.

On my linux laptop (Pop!_OS 22.04) using Chrome (ver 146.0.7680.164) I can flash all of the boards successfully, so this appears to not be an issue with the hardware.

Please let me know if any other information or tests would be helpful. Thanks!
