@mahmoud0100, your topic has been moved to a more suitable location on the forum; compilation errors don't relate to Avrdude nor to stk500 nor to the bootloader.

Why are you using IDE2.0 which is currently a beta version? You're probably a lot better of using IDE 1.8.15.

@mahmoud0100

when i try upload the code :

What code would that be ?

The easier you make it to read and copy your code the more likely it is that you will get help

Please follow the advice given in the link below when posting code , use code tags and post the code here

How to get the best out of this forum

Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. Please read and follow the instructions below. Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is frustrating for you and frustrating for us. The people who try to help with your pro…

If you get errors when compiling please copy them from the IDE using the "Copy error messages" button and paste the clipboard here in code tags

It looks to me like the linker can't find a "WiFi.h" that works on the "ESP32_DEV" board. Perhaps it needs "WiFiNINA.h" instead?

Serial port COM1

That's weird.

Start off with the ESP32 unplugged from the USB port and the Arduino IDE closed.

Open the IDE, note the serial ports, plug in the ESP32 does a new serial port show up?
