I don't really know why this is happening or even what's happening, how do I fix this?

I am using Unity 2020.3.4f1 and this is me attempting to do Ruby’s adventure ( I made my own project via unity hub) if anyone knows why this is happening and how to fix it, I would greatly appreciate that. (the first image is the error message while the second is where clicking on it takes me)

Yuck… looks like an error in the PSD importer… might want to try reimport all? Or if you’re not using specific packages then remove them? The trouble is (of course) understanding which packages you’re using and which you can just get rid of because they’re noise.

Here’s my standard blurb on these package errors, which has a flush package cache note at the bottom.

Perhaps someone with more pointed knowledge about Ruby and her adventure can chime in?

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:

Thanks for the info!
