New input system v[1.0.2] is having mouse issues in UWP build Unity v 2020.3.23f1,every time a new scene is loaded the mouse stops working, coming back only when you press a mouse button or move quickly, as soon as the scene loads and the standalone build does not have this problem. The way I’m using it is creating an InputMaster script, and adding the variables in static, and getting the InputAction values and passing them to the variables, through Update()
Input System 1.0.2 is quite ancient. Did you try upgrading to a newer version of that package?
Yes i updated to latest version of input system v 1.3.0 and still there was the problem.
