Bug Path must be located in Assets/ folder error whenever trying to create input actions.

Greetings,

I have a new Unity 2023.3.23f1 2D URP project. I have installed the Input System and rebuilt the backend.
After adding a PlayerInput component and clicking Create Actions, no matter what I name it or what folder I select (even accepting the default folder Unity wants to put it in) I get this error:

Path must be located in Assets/ folder (got: 'F:/dev/Unity Projects/Tutorials/Joust/Assets/test.inputactions')
UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&)

I have rebooted, restarted Unity and consistently get this error.

I have done this several times in other projects so I'm baffled.





Any ideas?

 

I had the same problem, and I solved it by moving my work environment from an external SSD to my C drive. I think it's probably a read or write permissions issue.
