Getting "Your session has expired" message trying to save login

I found the problem in my case and it seems that it was my fault.

I use a script, that removes a registry key from "HKEY_CURRENT_USER", so my company does not detect 1Password as installed Software.

I saw in developer console, that the extension cannot find the App.
So I restored the key and voila, the extension gets instant connection to the app.

I now just removes the displayname value from the registry for the software scanner and the app still works as expected.

The complete path must be there:

Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\1Password

May this information is helpful for anyone.

Again thanks for support and sorry for the circumstances 😁
