I have just started to get this error message after the latest Insider update to-day.
However Enpass seems to be working fine as even after clicking on the Ok button an is allegedly closing the app it still opens .
I have also been suffering for some time with being told there is a problem if I click on the Edge button but once again Enpass works after clearing the message.
Another weird thing is that when I click on the edge button my file explorer starts up, not sure if it is connected with the other problems but I thought I would throw it in for free.
