Yes. Seems to be problem in the new "show battery at connection time" change WHEN the default profile is not found for some reason at connection time.

Localized reasource string "NotUsingProfile" has "Controller {0} is not using a profile. Battery level is {2}%" value, but the code supplies only two input parameters:
string prolog = string.Format(DS4WinWPF.Properties.Resources.NotUsingProfile, (ind + 1).ToString(), $"{device.Battery}");
The "Battery level is {2}" should be "Battery level is {1}" in this NotUsingProfile resource string.

However, what I don't understand is why default profile file (xml file in settings folder) is not found there?
What do you see in "%APPDATA%\DS4Windows\Profiles.xml" file and in Controller1/Controller2/Controller3/Controlle4 options?
There should be a name of the default profile and a XML file like that should be found from Profiles subfolder.
Or do you have an empty default profile name value in Profiles.xml.Controller1-4 options?

As a quick workaround until fixed version is released try setting a valid profile name in at least Controller1 option in Profiles.xml file.

Version 2.1.7 fixes the initial problem.
