On Windows you have to manually install the appropriate driver for the USB to UART Bridge for some boards.
The default would be the CP2102 on an ESP32-WROOM-32 for example. Its driver can be found here silicon labs if i remember correctly. Have you made sure it is installed? Also make sure no other program that could access the board is running.
