nRF Connect For Desktop Bluetooth Low Energy v4.0.4-patch1 Blank screen

[Jelle DV]

Dear Nordic Team,

After reinstalling, debugging, and reading other posts about blank screens on DevZone, I've not been able to launch nRF Connect For Desktop Bluetooth Low Energy v4.0.4-patch1.

I think it's related to the error displayed in the console (Accessed through CTRL+SHIFT+I) "Not allowed to load local resource":

Is this something you have experienced before and do you know a way around this?

This is on Windows 11.

Best regards,

Jelle

Hello,

I recall a similar issue being present on Linux earlier - I will check this with the developers and get back to you! :) 

Best regards,

Hello,

We've ran a small test of this on a windows 11 comptuer which had no issue, so I am thinking that something went wrong during the installation. Could you clarify on the questions below?

Are you working on a corporate computer that may have very thight firewall settings, or similar?

When you say you reinstalled, does this mean that you reinstalled the full nRF Connect for desktop application, or only the BLE application within nRF Connect for desktop?

Are you able to find the file that 'could not be loaded' in the provided screenshot?

Best regards,
Karl

I'm not working on a computer with very tight firewall settings. I've already disabled windows defender even.

Yes, I've even removed '$HOME\.nrfconnect-apps' and everything in '$HOME\AppData\Local' related to nrfconnect.

Yes, I was able to find that file:

Ha!

I've been able to fix it now. What I did was:

1. Uninstall the BLE application within nRF Connect for desktop itself
2. Uninstall all the below packages through Windows Settings:
   
3. Remove  '$HOME\.nrfconnect-apps'.
4. Remove every folder I could find related to 'nordic' and 'nrf' in '$HOME\AppData\Local'.
5. Remove every folder I could find related to 'nordic' and 'nrf' in '$HOME\AppData\Roaming'.
6. Reinstall nRF Connect for Desktop with nrfconnect-setup-4.2.1-x64.exe.

I finally get this wizard again:
