Bug Description: While using the Greenshot editor, attempting to share a screenshot using the Windows 10 Share button leads to an issue when the user cancels the operation. After clicking outside the Windows Share dialog to dismiss it, Greenshot becomes unresponsive, and no further interactions with the application are possible. The only way to regain control is to use the Task Manager to terminate the Greenshot process. This problem occurs consistently even after a fresh installation of Greenshot.

Steps to Reproduce:

1. Capture a screenshot using Greenshot.

2. Open the captured image in the Greenshot editor.

3. Click the Windows 10 Share button in the editor.

4. When the Windows Share dialog appears, click anywhere outside of the dialog to dismiss it.

5. Attempt to use any function in the Greenshot editor.

6. Try closing the Greenshot application.

Expected Behavior:

• The Windows 10 Share dialog should close, and the Greenshot editor should remain fully operational.

• The user should be able to continue using editor functions or close the app normally.

Actual Behavior:

• The Windows 10 Share dialog hides but not closes, and the Greenshot editor becomes entirely unresponsive.

• The user is unable to perform any actions within the editor or close the application.

• The only way to resolve the issue is to forcefully terminate Greenshot using the Task Manager.

Attachments:

• Recorded video clip demonstrating the issue.

Additional Notes:

• The issue persists even after performing a clean installation of the Greenshot application (uninstalled and cleared each traces of previous installation then re-installed after system restart).
