When I upgraded my inputsystem from version 1.5 to version 1.51 from the package manager, many functions in my project could not be used, and the functions using inputsystem in the program seemed to be unavailable. And I can’t create new actions. I just started learning unity, please help me.
Go to Edit > Project Settings > Player There is a active input handling make it both if your functions are written in old input system this can be happen it disables old input sytem.
Or if it wouldn’t work just downgrade your input system to 1.5
