New Unity Install - Installed Input System plugin from Package Manager, now errors appear

Hi All,

As the title explains, I have a new unity install 2022.1.16f1. When I install Input System lots of errors appear in the console and I'm unable to proceed any further.

See the image below.


Here are some of the example errors shown above:
Library\PackageCache\com.unity.inputsystem@1.4.2\InputSystem\Plugins\XR\Devices\WindowsMR.cs(92,16): error CS0246: The type or namespace name 'QuaternionControl' could not be found (are you missing a using directive or an assembly reference?)

Library\PackageCache\com.unity.inputsystem@1.4.2\InputSystem\Controls\InputControlPath.cs(534,43): error CS0246: The type or namespace name 'Substring' could not be found (are you missing a using directive or an assembly reference?)

Library\PackageCache\com.unity.inputsystem@1.4.2\InputSystem\Controls\InputControlPath.cs(1154,22): error CS0246: The type or namespace name 'Substring' could not be found (are you missing a using directive or an assembly reference?)

Library\PackageCache\com.unity.inputsystem@1.4.2\InputSystem\Controls\InputControlPath.cs(1155,35): error CS0246: The type or namespace name 'Substring' could not be found (are you missing a using directive or an assembly reference?)

Library\PackageCache\com.unity.inputsystem@1.4.2\InputSystem\Devices\Joystick.cs(73,16): error CS0246: The type or namespace name 'StickControl' could not be found (are you missing a using directive or an assembly reference?)

Library\PackageCache\com.unity.inputsystem@1.4.2\InputSystem\Devices\Sensor.cs(285,16): error CS0246: The type or namespace name 'QuaternionControl' could not be found (are you missing a using directive or an assembly reference?)

etc...

These errors are coming from Library\PackageCache\com.unity.inputsystem@1.4.2\InputSystem

I have completed the following troubleshooting steps:

- Tried a new project
- Tried multiple versions of unity
- Removed Unity + Unity Hub
- Removed Unity and Unity files
- Restarted PC
- Installed the package from the GitHub repo

Nothing seems to rid of these errors.
I'm a little lost on how to proceed any further on this one and would love some assistance if possible.

 

Okay, so I looked into the menus and found this:
Help -> Reset Packages to defaults
Doing this option has resolved this issue.

Updating this if someone else runs into this issue.
