Arduino IDE COM Port error on Windows 10
An easy thing to try but might not help: Use another USB port of your computer and see if the driver is reinstalled.

Otherwise, go to control panel and find the drivers (Device Manager), search for the Ports (COM &amp; LPT) drivers and remove the driver for the Arduino manually, reconnect the Arduino and check if it is installed correctly. Possibly a wrong version of an Arduino driver is installed. If another driver is installed at COM3 (where is my Arduino), remove that driver and try again.
