Hi,
What is the model of your wireless mouse?
Please check if the mouse uses a USB dongle and is connected, or if it's giving an "unknown USB" error.
If it's Bluetooth, try adding it again > First, remove it in the Start menu > Settings > Bluetooth & devices > More devices > find the mouse > click on the "...", select "Remove devices" and wait for the process to finish.
Then select "Add devices", select Bluetooth, put the mouse in pairing mode and try to see if it identifies it.
If it doesn't appear, test it on your smartphone to see if it recognizes it.
