Does anyone from you know  why my razer blackwidow v3 mini hyperspeed start double typing after i install Synapse 4?

And how do I completely uninstall Synapse 4? - i already uninstall  Synapse 4, delete some leftover from windows registry, disconnect and connecting again the keyboard. Nothing work - now even without the software installed the keyboard does double typing

The thing is,  without software installed the keyboard worked perfectly.  - that was before i install Synapse 4 first time.

Operating system is Windows 11 25H2.
