IDE hangs on startup: "Error loading hardware platform: discovery builtin:serial-discovery not found"

electricalman · October 29, 2023, 8:13am

Arduino 2.0 will not start past the loading screen

I'm going to ask you to post some additional information that might help us to identify the problem.

Please do this:
Start Windows "File Explorer".

Open the Arduino IDE installation folder.
(usually C:\Program Files\Arduino IDE or C:\Users\<user name>\AppData\Local\Programs\Arduino IDE).

In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.

From the context menu, click "Open PowerShell window here".
PowerShell will now open with the current directory set to the Arduino IDE installation folder.
Type the following command:
& ".\Arduino IDE"
Press the Enter key.
Debug output should now be printed to the PowerShell window as the Arduino IDE starts (or fails to start).

Wait until you are sure the startup of Arduino IDE has hung.

Switch back to the PowerShell window if the Arduino IDE window took the focus.

Right click on the title bar of the PowerShell window.
This will open a context menu.

Select Edit > Select All from the context menu.
This will select all the text in the PowerShell window.

Press Ctrl+C.
This will copy the contents of the PowerShell window to the clipboard.

Open a forum reply here by clicking the Reply button.

Click the </> 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.

Press Ctrl+V.
This will paste the output into the code block.

Move the cursor outside of the code block markup before you add any additional text to your reply.

Click the Reply button to post the output.

Hi @electricalman. I see the problem here:

electricalman:

2023-10-29T07:42:49.780Z root ERROR Detected an error response during the gRPC core client initialization: code: 9, message: Error loading hardware platform: discovery builtin:serial-discovery not found

On the first run after a fresh installation, Arduino IDE downloads some additional essential components from the Internet and installs them. If it can't install those components then the startup fails. So the computer must have access to the Internet on the first startup.

The errors indicate Arduino IDE is not able to access the Internet. If it is not already, please connect your computer to the Internet, close the Arduino IDE window, then start Arduino IDE again. This time it should start up successfully.

After that first run, an Internet connection is not required. However, there are some supplemental features such as "Library Manager" that have an inherent dependency on the Internet. Those features will not be usable while your computer is offline. But the essential functionality of editing, compiling, and uploading sketches will be available even without an Internet connection.

Thanks, it worked. Please I'm encountering another little problem here. I'm trying to install ESP32 library on my IDE but it keeps up popping this error message.

You are welcome. I'm glad the IDE is able to start up now.

This problem might be caused by your firewall or some other network security system (e.g., proxy or VPN) interfering with Arduino IDE's ability to access the Internet.

Are you aware of anything special about the configuration of the network you connect to the Internet through that might interfere with Arduino IDE's access to the Internet?
