Windows 10 Calculator not working

Hello,

If a default Windows 10 app is missing or not working correctly, it might be due to the system being outdated or there is a corruption within the system or profile that you are using. For us to isolate the issue in launching the Calculator app in Windows
10, kindly respond to the questions below:

• Did the problem in opening the app started recently?
• When attempting to open the app, are there any error messages that appear?
• Are you able to launch the app using another local account?

As a first troubleshooting step, we suggest that you check if there are updates that are waiting to be installed on your device. If there are, kindly install them and restart your device. After restarting, attempt to launch the app.

We look forward to an update from you.
