when update win 10 to 1901 version arduino IDE dont work normal and dont detect device

[elagh]

i update win 10 to 1901 version, Then the software knows the common port, but does not identify the arduino device ( arduino pro mini 5 v).
(i test the unio and mega series but The problem remained.)
and Arduino IDE show the ""avrdude: ser_open(): can't open device "\.\COM10": Access is denied."" error.
first i think my device has problem but change the devices but The problem remained until I reviewed the program from another computer with the Windows version 1809 and there was no problem.

• before update windows i dont have any problem.

Hi @elagh ,
it Win10 1901 a real version? I could only find 1903 as the latest available and I'm preparing a PC with that version to test the issue.

It works fine and no problems of driver.

Caused by: jssc.SerialPortException: Port name - COM4; Method name - openPort(); Exception type - Port busy.

Only one thread can access a COM port at a time. Quite likely another program is using your COM port, please download the Portmon utility from Microsoft and check if you can see any process as the culprit for using your COM port.
