I keep getting an error that doesn't appear to cause issues but I'd still like to verify that statement and also know how to stop it from appearing

MonoScriptImporterInspector.OnEnable must call base.OnEnable to avoid unexpected behaviour.
UnityEditor.Tilemaps.GridPaintPaletteClipboard:OnDisable () (at Library/PackageCache/com.unity.2d.tilemap@1.0.0/Editor/GridPaintPaletteClipboard.cs:347)

It would appear to be an issue with something in the tilemap library, does it matter? Would it be fixed via re-importing?

@penguin137, did you ever figure out what the problem was? I get this exact error with a fresh tilemap project in Unity 2020.3, even before any colliders are added.

this type of errors usually get fixed updating to latest lts version and using packagemanager to update the specifiq package.

@penguin137, Using the wrong box collider can cause this error. make sure they are all box collider 2D.
