IDE says the the com port does not exist when uploading to ESP32

[Elesoft]

i have an ESP32 with a mini USB port and CP2102 chip.
I can see the data delivered by the ESP on the serial terminal of my IDE BUT when I do try to load the sketch my IDE says the the com port does not exist ! ( no possibility to upload ).
Any help / suggestion please ?
( i have already updated the CP2102 driver, reset the PC, reset the ESP , changed the USB cable and PC port with no improvements )
Thanks

Hi @Elesoft. I'm going to ask you to provide the full verbose output from an upload attempt.

This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
   The "Preferences" dialog will open.
2. Uncheck the box next to Show verbose output during: ☑ compile in the "Preferences" dialog.
3. Check the box next to Show verbose output during: ☐ upload.
4. Click the "OK" button.
   The "Preferences" dialog will close.
5. Attempt an upload, as you did before.
6. Wait for the upload to fail.
7. You will see an "Upload error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
8. Open a forum reply here by clicking the "Reply" button.
9. Click the <CODE/> icon on the post composer toolbar.
   This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
   
   
10. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
    This will paste the error output from the upload into the code block.
11. Move the cursor outside of the code block markup before you add any additional text to your reply.
12. Click the "Reply" button to post the output.
