uploading to esp8266 fails

Start with the PlatformIO upload output for main.cpp and the ESP8266 esptool stage, especially the SerialTimeoutException raised while writing at 8%. Check the reported platform, board, COM4 port, and upload configuration; done means the firmware uploads successfully without the timeout.

can someone help me with this error when trying to run a simple blink code to esp8266 using platformio in vs code
