Following the latest update I have had issues with applications being blocked from accessing the internet even though it appears there is a firewall rule allowing access. When I edit the rule I discover that the program path contains an incorrect drive letter - either a valid drive but not the location of the program file or a drive letter that does not exist on my machine.
I have to keep manually editing the rules to correct the program paths.
In addition, when I run the firewall in alert mode and click on "view application" the application cannot be found and I am presented with Windows explorer showing the "This PC" screen.
