Having problems with ESP32

Development Tools Uploading

Hello, i'm having problems with a led blinking code using a Mini D1 ESP32.

In short, everytime i try to upload, using my laptop, it gives me this error:

Sketch uses 236793 bytes (18%) of program storage space. Maximum is 1310720 bytes.
Global variables use 21048 bytes (6%) of dynamic memory, leaving 306632 bytes for local variables. Maximum is 327680 bytes.
esptool.py v4.5.1
Serial port COM3
Connecting...

A serial exception error occurred: Write timeout
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

Failed uploading: uploading error: exit status 1

The funny thing is that i tried it on my other PC and it works, so at least i know the problem is not the cable or the board itself.

Anything could help.

change usb cable, ensure you have the right port selected, do you have the right driver, is the right board selected, ...

I have the same problem. I tried the solution on ESP32S3 no connection error - #7 by salvatore_zuccaro, but it did not work. My issue is also ONLY on laptop
