Question InputSystem does not contain a definition for SaveAndReset

Getting an error out of the blue when trying to build Addressables relating to the Input System. Worked perfectly fine prior to the time of writing. Updated everything in the Package Manager (except Addressables).



Unity 2020.1.15f1
JetBrains Rider package 3.0.24
Input System 1.6.3

 

This is an excellent first step... this is an even-excellenter second step:

Extra unwanted packages in new projects (collab, testing, rider and other junk):

About the fastest way I have found to make a project and avoid all this noise is to create the project, then as soon as you see the files appear, FORCE-STOP (hard-kill) Unity (with the Activity Manager or Task Manager), then go hand-edit the Packages/manifest.json file as outlined in the above post, then reopen Unity.

Sometimes the package system gets borked from all this unnecessary churn and requires the package cache to be cleared:

I was able to fix the issue by reverting my package changes in source control. Probably more of a workaround than an actual solution, but it works for now.
