I started face with this issue after recent Microsoft updates. On my Asus Rog Laptop with Windows 11, it usually restarts due LSP not signed issue after Windows Installer reconfigures Microsoft Game Input even though i disabled or delete any related services, files or stop any tasks. I've done quite many steps here and there through registery, command and configuration. After spending tremendous amount of attempts until Microsoft finds a solution i found this solution works for me;
Unplug the power cable and run the laptop on battery. ( Strange, isn't it ? )
Hope that is works for anyone out there having the issue. It is a real bugger.
