Hi Dan,
There could be a number of factors as to why you are having issues launching the Calculator app on Windows 10. This could be caused by a software conflict or due to the application itself.
You may consider resetting the Calculator app. To do this, refer to the steps below:
- Go to Settings > Apps > Apps & feature.
- Click the Calculator app from the list and then choose Advanced options.
- Click Reset.
If the issue persists, I suggest that you create a new user account. This is for us to check if the issue is due to a corrupted user profile. To do this, select the Start button, then select
Settings > Accounts > Family & other people > Add someone else to this PC.
Let us know how it goes and we'll assist you further if needed.
