Uninstalling platform causes IDE to stop working

[AlbyIanna]

Describe the problem

Sometimes, if you have a selected board that belongs to a platform and you try to uninstall that platform, the IDE will stop to work. No useful feedback is given, the platform will appear to be installed and any action you perform that uses the backend (like compiling a sketch, creating a new file or updating a library) will fail. Quitting the IDE and reopening it will show that the platform has actually been uninstalled.

To reproduce

I wasn't able to reproduce it consistently because sometimes it works just fine, but repeating the steps a few times would always lead to the reported error.

1. Open the Boards Manager from Tools > Board > Boards Manager...
2. Search and install the Arduino MBED OS Nano Boards platform (only if you don't have it already installed)
3. Select the Arduino Nano RP2040 Connect from Tools > Board > Arduino MBED OS Nano Boards > Arduino Nano RP2040 Connect
4. From the Boards Manager, UNINSTALL the Arduino MBED OS Nano Boards
5. 😢 Output in the console says boards are uninstalled, but the Arduino MBED OS Nano Boards in the Boards Manager still looks installed and the menu item Arduino MBED OS Nano Boards is still present in the Tools > Board menu. Also major IDE features will stop working.

Expected behavior

1. Open the Boards Manager from Tools > Board > Boards Manager...
2. Search and install the Arduino MBED OS Nano Boards platform (only if you don't have it already installed)
3. Select the Arduino Nano RP2040 Connect from Tools > Board > Arduino MBED OS Nano Boards > Arduino Nano RP2040 Connect
4. From the Boards Manager, UNINSTALL the Arduino MBED OS Nano Boards
5. 😸 Output in the console says boards are uninstalled, and the IDE won't stop working

Arduino IDE version

2.0.1-nightly-20221006

Operating system

macOS

Operating system version

12.3.1 (21E258)

Additional context

This bug never happened to me when I had a selected board from a different platform.

Also, I want to make clear that this bug didn't happen consistently to me, sometimes I met the expected behaviour, sometime I didn't.

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

Same as #1529?

[AlbyIanna]

I don't think so. These the errors I get from the backend:

It doesn't look the same as #1529, right?

[kittaakos]

Are there any errors in the backend logs, or only the Connection dropped and No connection established?

Update: I downloaded the Version: 2.0.1-nightly-20221006 Date: 2022-10-06T03:31:43.138Z build and installed/uninstalled various platforms, but could not reproduce it. Please share the instructions if you figure it out. Thanks!

I see only those two errors.

Please share the instructions if you figure it out.

As wrote in the PR description, I haven't figured out how to reproduce it consistently, I just know that if I repeat the steps in the To reproduce section, usually after at most a couple of times I get this error. That's the all the context I can give for now, but as soon as I discover further information I will write them here.

In case you want more information about the cause of an error from the @grpc/grpc-js package, there are some environment variables that control the verbosity of the output:
