1Password Windows App does not appear

Hi PassFischKopp! It's great to hear that disabling hardware acceleration got things working for you 😄

Based on this, it sounds as if you were running into a known issue our developers are currently investigating where the 1Password main window fails to open reliably on some devices when hardware acceleration is enabled. It's unclear yet why this happens, and we do apologise for any inconvenience caused. I've gone ahead and added your case to the issue on file for the team to see.

I'm not yet able to provide a timeline for a fix for this issue, but you can keep an eye on our release notes for news: 1Password Releases

In the meantime we would recommend keeping this option disabled, and if you run into the issue again let us know!
