Hello Mattie, this is Emily.
Sorry you are experiencing this issue with the mouse. Looks like Windows can't find the right driver for your mouse to work in Windows 11. You said you went to Logitech to download the software, is it specifically the driver though for this model of mouse? I am afraid this is something you need help from Logitech support instead, to find out if there's any incompatible issue running their product in Windows 11.
