I suggest you go through the below steps to resolve this issue, also, please check if the mouse works fine on another device, and keep me posted;
- Go to Settings>System
- Now go to Power & Sleep tab
- Uncheck both “On battery power, stay connected to WiFi while asleep” and “When plugged-in, stay connected to WiFi while asleep”
