IDE hangs on startup: "discovery builtin:serial-discovery not found"

Software IDE 2.x
1

Hello everyone.
It just so happens that until recently I was using Arduino IDE version 2.3.2 and 1.8.xx at the same time.

But lately, when I launch the IDE version 2.3.2, it gets stuck in infinite loading, only showing the Arduino logo and won't start.

Here's the code I found on the forums, and it says to attach the code, so I'm using SHELL to attach the code.

I'm wondering what issue is preventing it from running... I would like to use an IDE.

Hi @123142123124

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 indicates some of those components are missing. If it is not already, please connect your computer to the Internet, close the Arduino IDE window, then start Arduino IDE again. Hopefully after that the IDE will 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.

Won't run on first startup
I've tried reinstalling after an infinite load, and it's the same infinite load. Is there any other workaround? Is there any way to add that library directly?

4

You need to turn on Arduino to install Library Manager!

Is the developer not responsible, or is it just time-consuming.

Hundreds of people are pointing out that the program isn't working. I'm still using ver 1.8.x.

Is it a desirable form to distribute programs that do not work even with this behavior.

Does the CEO of Arduino know about this? When will it be resolved? I'm inquiring.

Even if there's a little error, can't you turn on the program and fix it!

5

Did you try the thing I told you to try?:

6

It is working perfectly for many, many thousands of people, including myself. The 99% it works for don't have any reason to post about it so all we see are the reports from the 1% who have some sort of unusual system configuration that causes a problem.

I do my best to support that minority.

Are you having some problem with Arduino IDE 2.x? If so, you are welcome to provide a detailed report of the problem in a dedicated forum topic and I'll try to help you out. If you are able to provide assistance in solving @123142123124's problem, you are very welcome to contribute, if not, please move on to other threads since your participation in this one so far is not productive.

This is free open source software. If you think you can fix it, then you are welcome to submit the fix. You can learn how from this guide:
