Hi Alex,
Welcome to Microsoft Community.
Thank you for providing the detailed description of your issue. It sounds like you've already tried several troubleshooting steps. Here are a few additional suggestions that might help:
- Safe Mode, which starts Windows in a limited state, where only the bare essentials services and drivers are started. If a problem doesn't reappear when you start in safe mode, you can eliminate the default settings, basic device drivers, and services as possible causes. Windows startup settings - Microsoft Support
- Try Another Device: Connect the mouse to another computer to see if the issue persists. This can help determine if the problem is with the mouse or your computer. If none of these steps fix the problem, you might consider contacting Microsoft Support, or if it’s a hardware issue, you might need to replace your mouse. Contact Us - Microsoft Support
I hope this helps. If there is anything not clear, please do not hesitate to let me know.
Your Sincerely
Hahn. W - MSFT | Microsoft Community Support Specialist
