I installed the today´s update of Windows 11 Insider preview and after the installation the WhatsApp Web stopped working. It´s only opens an white screen a do not complete the initialization.
I already use the Repair, Restore and Uninstall options available on Windows Settings, but it doesn't work. After uninstall I used the app available on Microsoft Store.

The Windows build is 26.220.8138.ge.release_scv_betafit_prod1.260325-0357
Is there a fix tor this problem?

Windows Insider program | Apps on Insider preview

    Hi Hamilton,

    We/I have to contact with WhatsApp Developers.

    You would have to report it to WhatsApp Support.

    Hello CrazyKats.

    **I just **uninstalled the last Insider update nº KB5079491 update and WhatsApp Web started working again immediately.

    My conclusion is that the update KB5079491 has some issue. Can you report it to Microsoft Developers?

    Thank you for helping.

    Hi Hamilton,

    Whatsapp is not a Microsoft product.

    It's up to Whatsapp to make it work with

    Microsoft, not Microsoft to make it work.

    You can file Feedback in the Feedback Hub,

    Or uninstall the last Insider update if it worked

    on the last build.
