Strange behaviour at startup and generating Windows error message randomly


I am a very long time user of 1P and moved recently to a new laptop Thinkpad X280 under Win10 Pro (French).

I am encountering strange behaviour with the main 1P software (latest version available 7.3.684) as I deselected the option "open at startup" in the settings but still the login 1P window is there every time I start up the laptop. When I enter my password, the program closes down and generates an error reprot that I am sending to Agilebits without getting any feedback.

When you launch it for the second time, the program will work correctly but will then randomly tigger Windows error message related to NET framework I guess (or something similar). I must confess that I didn't pay much attention to the details as the error window seemed very complex in its formulation...

I have generated a log file that I can send to the support if you provide me with the explanation on how to do it.

Thanks in advance and best regards.

1Password Version: 7.3.684
Extension Version: 1.15.3
OS Version: Win 10 Pro
Sync Type: 1P .com

    Hi @Didiko,

    Thank you for reaching out! :+1:

    We will need to investigate what is happening, so please send your Diagnostics Report in an email message addressed to [email protected]. Additionally, try to take a screenshot of that error message the next time you see it, as it will be really helpful. Here is how you can use Snipping Tool to capture screenshots:

    If you see "This application could not be started" error message, please try to uninstall 1Password extension from Microsoft Edge, reboot your PC, and check if the issue remains. Thanks! :+1:
