  1. Open the Windows Settings app and go to Apps > Installed Apps.
  2. Find the problematic application.
  3. Click the three dots and choose Advanced options or Modify (if available), then select Repair.
  4. If a repair option is missing, click Uninstall, restart the PC, and install the application again using its official setup media.
