Hi
Welcome to the Microsoft community.
These two shortcut combinations are not the screenshot combinations that come with Microsoft. Have you used some third-party software to assist you in taking screenshots before? You can refer to this article for the shortcut keys of the Microsoft screenshot tool.

If you want to use this shortcut to take a screenshot, you can use the screenshot function of Edge, which should not be saved locally. You can refer to my settings to go to this website to set related functions.
