Microsoft Edge won't open

The issue persists King?

Did you already tried power cycling your console to see how it goes?
1. Turn off your console by pressing the Xbox button on the front of the console for about 10 seconds, until it shuts down completely.
2. Unplug the console's power cable from the console and from the power outlet. Wait 5 minutes.
Important: Be sure to wait at least 5 minutes. This step resets the power supply.
3. Plug the console power cable back in.
4. Press the Xbox button on your console to turn it on.

Aftert that, try to remove and re-add your profile on the console.

In case you need it, here's how to remove and re-add:

Or change temporarily your region to another and test

It happened on my xbox one

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today King

In which device is this happening?
Xbox or PC?
Microsoft Edge app icon is the newest one?

I'll look forward for your reply, greetings from another Microsoft user!

Open the Microsoft edge app.

When I open the browser, using Xbox Series S, in the upper right corner there are 3 dots (...). From those dots a box opens saying it was unable to update the browser and to reinstall Microsoft Edge. The link takes you to a Microsoft page where you can download Edge, but you have to first select a Windows version. Xbox is not listed as it's a modified Windows operating system.

If you "X out" of the notification Window saying it was unable to update and to reinstall Edge. There is a red notification tag on the 3 dots in the upper right hand corner indicating something needs to be done. When you click on the 3 dots at the top of that menu it says "Microsoft Edge is out of date". When you click on the message it opens the box telling you to reinstall Microsoft Edge.
