    Hello, hieu nguyen.

    Perform a small check.

    Open the Mouse Control Panel. On the "Mouse Buttons" tab in the "Button Configurations", enable "Exchange button assignment". Apply the changes and restart your PC. The functionality of the mouse buttons will be reversed. Watch the work (it will be unusual at first). If the physical left mouse button also works intermittently, it means that the mouse button itself is defective. And in this case, either repair the button or replace the mouse with a new one.

    P.S. English is also not my native language, so I also apologize if something is wrong)))

    Dear hieu nguyen

    Thanks for reaching out! Welcome to Microsoft Q&A. I'm Haien from Microsoft Q&A. 

    I understand how frustrating it is when your mouse isn't working as it should. Your English is perfectly understandable, so please don't worry about that at all! From your description, it sounds like the problem is with the mouse itself, rather than a Windows issue, especially since you've already tried resetting your PC. The way the left-click sometimes works and then causes the app icon to get smaller is a classic symptom of a faulty physical button.

    To sort you out, could you let me know what is your Windows version (Windows 10 for Home or Windows 11 for Home)? In the meantime, you can try these effective workarounds and let me know anything news with each step:  

    • Test the Mouse on Another PC > Try a Different USB Port or a Different Mouse
    • Press the Windows key + X and select Device Manager > Expand the Mice and other pointing devices section > Right-click on your mouse (e.g., "HID-compliant mouse") and select Update driver If that doesn't work, right-click and select Uninstall device > Restart PC
    • Search for Mouse settings in the Start menu and press Enter > Select Additional mouse options > In the Mouse Properties window, go to the Buttons tab and uncheck the box next to Turn on ClickLock.

    Please keep me updated with anything new that you were try to each option.
