I attempted to fix this problem using Windows Device Manager. I was able to successfully uninstall the device and the driver. When I reconnected my Arduino Uno R3 the same driver installed (ver. 3.8.2023.2) and I was unable to upload and got the same error.
I found an older driver on the Sparkfun site How to Install CH340 Drivers - SparkFun Learn
and installing that driver solved the problem. The driver that installed and worked is ver. 3.4.2014.8 dated 8/8/2014.
