Unity build issue
Due to an error (or rather 55 errors) I can't do a build (see screenshot where a part is shown)
Unity Version: 2022.2.21)
I had the same issue.

This website says the solution is to just delete the folder 'Editor'. In my case, 'Editor' folder was in the path 'Packages\UnityChanSpringBone-release-1.1\Editor'. So I deleted the whole Editor folder and no more build errors occurred.

Doing as you suggest prevents usage of Editor features for the package. The correct solution is to ensure that only the Editor target is checked in Editor/com.unity.animations.springbone.editor.asmdef.
