1password v. 6.4.377 doesn't open Windows 10

Hi! Since the last update on 1password it seems i can't open it on my PC. All I have is a blank screen... I tried to reinstall / deleting all files in the directory but it doesn't seem to work.

1Password Version: 6.4.377
Extension Version: Not Provided
OS Version: Windows 10
Sync Type: iCloud

    Hi there @Red_Blade,

    Thank you for reaching out! :+1:

    We've seen blank white screen in 1Password being caused by some graphics drivers, Riva Tuner (nVidia's software), and anything that can impact how the application's windows is rendered. In 1Password 6 we use Windows Presentation Foundation, which relies on Windows' graphic subsystem, which uses your GPU to render the apps. Do you have anything like that?

    Please try to uninstall your graphics drivers, reboot, let Windows install the default drivers for your GPU and test 1Password. Let us know if the issue with the blank screen remains after that. Thanks in advance!


  • My graphic card is an Intel HD Graphics 520.

    I rolled back to a previous version of the driver and it worked! Thanks!
