Step 1: Navigate to Settings app > Apps > Apps & features.
Step 2: Locate the Microsoft Store entry and click on it to reveal the Advanced options link. Click the Advanced options link.
Step 3: In the Reset section, click the Reset button. As you can see in the screenshot, the description clearly says that resetting the app will reinstall the app. Click the Reset button when you see the confirmation dialog to complete the reinstall.
Thanks
