1Password can no longer launch or uninstall or update, application error

@rijtan That doesn't sound right at all!

Sometimes this can happen if anti-malware is installed on the machine; I see you've mentioned Malwarebytes there, but before we jump to any conclusions I think it would be best if we could look into this with you on a 1:1 basis.

Since I can not launch 1password, I can not provide the requested diagnostics data.

Not to worry, we can still get some logs from you and troubleshoot this. :+1:

Could you write in to us at support+windows@1password.com, and reply to this thread with your ticket ID? It should look something like [ABC-12345-678]

We'll then pick things up and see what's going on. :)
