IDE hangs on startup, with no error shown in logs

Development Tools IDE 2.x

Sorry for yet another post, but I believe I looked through all and cannot find the solution.
Here's the snap from the PowerShell.
I turned off all Windows Security features without luck.

Is that the full output? It does not show any errors as far as I can see.

Can you provide a little bit of history? Did you upgrade from an earlier version (e.g. IDE 2.2.2) or is this a fresh install?

3

Yes, full output, no errors :frowning:
I reinstalled twice already - deleting all Arduino IDE files - incl. appdata and .arudinoIDE and registry.
Reverted from the windows update this morning - KB5044033 - no luck.
Deleted OneDrive and reassigned the Documents folder to local - no luck
Reinstalled OneDrive - no luck.

To be honest, I have no idea.
> If it exists, did you delete C:\Users\yourUsername\AppData\Roaming\arduino-ide as well?
> Which Windows version are you using?

If you want to try a previous version, you can download previous releases from Releases · arduino/arduino-ide · GitHub. Download the ZIP of e.g. IDE 2.3.2; ZIP installs provide an easy means to uninstall by simply deleting the directory where you extracted it; you will still need to manually cleanup all other stuff.

5

Yeah, deleted the C:\Users\yourUsername\AppData\Roaming\arduino-ide - no luck
I'm on Windows 11.
It was running yesterday :frowning:
I tried 2.3.1 today. No luck :frowning:
Spent an entire day on int :frowning:

6

My guess it's stuck at the /services/ide-updater
But I do not know where and how to fix it.

7

Neither do I :slightly_frowning_face:

What changed? The Windows update that you uninstalled? Update of board packages?

8

Installed version 1.8.18 and it's working just fine
