Hi,

Thank you for contacting Microsoft Community.

I understand your inconvenience. We will assist you with it.

Please share the detail.

• Which application you are referring to?

Method 1: Windows has a built-in troubleshooter to check and fix issues with system. I would suggest you to run this troubleshooter to check if the issue is with your System Maintenance.

Refer these steps:

• Press Windows key +X, select Control panel.
• Change the view by option on the top right to Large icons.
• Click on troubleshooting and click on the view all option on the
  left panel.
• Run the System Maintenance troubleshooter.

If the issues persist try next method.

Method 2: I would suggest you to perform a clean boot and check.

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.
