Bug Input Debugger Bug

I can't run input debugger. The window is empty and there is an error in the console. The problem appears in any project on any version.

I have the same issue on 2021.2.10f1

 

For those looking for a fix, try right-clicking on the "Input System" folder in Project - Packages, and select "Reimport All".
