I have Windows 10 and 1Password 7, which has worked for some time. I think it may recently have been automatically updated to version 7.3.657 (that's what it says when I right click the desktop icon). However, when I try to open the app, I get an error message "Error: IO error Access denied. (os error 5).
The browser add on (Chrome) still works, and the app still works on my android devices.
