Arduino IDE broken after 2.3.2 update (Mac/ARM)

myklemykle · March 22, 2024, 6:54pm

I updated Arduino from 2.3.0 to 2.3.2, and it hung on restart. Shortly thereafter the entire Mac UI froze, which almost never happens ... that may have been some other transient OS issue, I don't know if I can pin that on Arduino. But at any rate the first startup of 2.3.2 did not complete at all.

My Mac was functioning properly again after a reboot. But when I launched Arduino it came up in some useless half-installed condition.

The IDE windows open but there are no libraries, no boards.
The preferences pane is blank.
I can't open a sketch
I can't even quit the IDE

Starting the IDE from a shell, I get a ton of console output but no obvious (to me) explanation. I've included that below.

I reinstalled 2.3.2 manually from the download image, but nothing improved.

Then I reinstalled the older 2.3.0 image, and everything worked normally again.

I figured why not try the IDE auto-upgrade to 2.3.2 one more time?
But the result was the same: a broken install, missing a bunch of parts.

Then I manually installed 2.3.1 over 2.3.2, but the result was the same.

Manually installing 2.3.0 over 2.3.1 once again fixed the problem. So some change between 2.3.0 and 2.3.1 seems connected to this problem.

I've read a few other reports where people said that if the first startup of 2.3.2 doesn't run perfectly, things can be screwed up. But how would I fix such a screwup? Obviously reinstalling doesn't help.

Thanks,

Hi @myklemykle.

Unfortunately it is the same for me. It looks like the output we would expect when the IDE is in a functional state. It is possible the problem is caused by some problem in the Arduino IDE application configuration data. If so, it should be possible to restore the IDE to functionality by deleting the folders where the data is stored. This will force Arduino IDE to automatically regenerate the default configuration data.

Please try this:

The folders to be deleted do not contain any of the data for your sketch projects so deleting them should not result in the loss of any irreplaceable data. However, please always be careful when deleting things from your computer. When in doubt, back up!

Close all Arduino IDE windows if the IDE is already running.
Delete the folder at the following path:
```
/Users/<username>/.arduinoIDE/
```
(where <username> is your macOS username)
The .arduinoIDE folder is hidden by default. You can make it visible by pressing the Command+Shift+. keyboard shortcut.
Please be careful when deleting things from your computer. When in doubt, back up!
Delete the folder at the following path:
```
/Users/<username>/Library/Application Support/arduino-ide/
```
(where <username> is your macOS username)
The Library folder is hidden by default. You can make it visible by pressing the Command+Shift+. keyboard shortcut.
Please be careful when deleting things from your computer. When in doubt, back up!

Now start Arduino IDE again. Hopefully this time it will start up fully.

The Arduino IDE preferences will have been reset to their default values. If you had previously made any customizations to the preferences (e.g., the "Additional Boards Manager URLs" preference) then you will now want to reconfigure the IDE as necessary.

Please let me know if you have any questions or problems while following those instructions.
