Strange that my basilisk stopped working today. Some conflict with synapse3. If you uninstall it, it goes back to normal. I install it again and it crashes again. I also tried the beta.

Is it visible in Windows device manager?

The synapse? When installed, yes, but I had to uninstall it. Just install it and the mouse will stop.

No, windows device manager, not synapse. If it's not visible there it may be some hardware problem with the mouse.

the mouse appears normal
