As you can see from the above pic, there are some unrecognized icons showing in the windows 11 taskbar. There are two apps that do not have recognizable icons one was Edge app and the other one was the Chrome app.
It creates confusion when I was working with a lot of apps.
I have tried pinning that unrecognized icon. the first time it worked and the second time no luck.
And also I have tried all the workarounds which were listed in the video but still no luck.
