Errors are Constantly thrown when Active Input Handling is set to Input System Package

Package: Scriptable Render Pipeline Universal


How to reproduce:
1. Create a new URP template project
2. Open Project Settings > Player > Active Input Handling and set it to "Input System Package (New)"
3. Play the Scene

Expected result: Editor plays the scene without any errors
Actual result: Editor is constantly throwing errors

Not reproducible with: 2018.4.7f1, 2019.2.2f1, 2019.3.0a5
Reproducible with: 2019.3.0a6, 2019.3.0a12, 2020.1.0a1
Could not test with: 2017.4(No Package Manager)

Reproducible with package versions: 6.5.3, 6.7.1, 6.9.1, 7.0.1

Workaround: Setting Active Input Handling to "Both"

1. The issue only happens if Active Input Handling is set to "Input System Package (New)"
2. Can also be reproduced after removing URP/LWRP.
3. The issue seems to occur with every URP/LWRP version when 2019.3.0a6 or above is used

    Reimporting the URP 7.2.1 package as suggested on a forum post seems to have resolved my issue.

    I'm in the process of switching over to new input system and this is popping up in my project now as well. I did not have UDP or HDRP installed in the project when I brought in the input system, it was only in the project prior but removed before input was changed.

    Never mind, the issue was fixed after a reimport all.

    Unity's internal scripting define symbols do not get updated until the entire project is reimported. This is because the system was designed for platform dependent compilation, and when the editor switches platforms a reimport all is performed.

    You can fix the issue with right click -> reimport all in the Project window or by deleting your project's Library folder.

    Still happening in URP 7.2.1. This is ridiculous, this is not a hard problem for Unity to fix.

    Could it be this also causes the stacktrace every update?

    Issue still exists in URP 7.1.8. Common guys, this needs to be fixed.
