TinyCLR Config crashes with SCM20260

TinyCLR version is 2.4.0.1000

When I try to do a firmware update, it gives the following error message

Can’t connect to the device. Refresh port and connect again.

When I do try to reconnect it is still in loader mode and when I select the port, it crashes. The event viewer shows this in one of the logs:

I am unable to update the firmware.

I can’t even connect and erase all.

Somehow your PC has a USB port conflict. In Device Manager, uninstall the COM port driver and let it be automatically recognized again. If that doesn’t help, try using a different computer to check.
