After using tilemap, can't select game objects in scene view normally until I close and re-open scene tab.

Questions & Answers

I don’t believe it’s a layering or UI issue. I simply can’t click anything in the scene view with left-click. I can still click go’s in the hierarchy and move them that way, however.

unity 2021.1.10f1

Suggestions?

Same for me!
If I close the tile pallete window I can select items in the editor view again.
Just going to a different tab (hiding the tile pallete window) is not enough.

I also had this issue. I was able to fix it but I had to embed the tilemap package in my project and edit the GridPaintPaletteWindow.cs file. You can find the tilemap package in your project folder /Libarary/PackageCache. Copy and paste the com.unity.2d.tilemap@1.0.0 folder to your project folder /Packages. Seems to be a problem with the PaintableSceneViewGrid. In the ActiveToolChanged method, I added this to the end:

// PaintableSceneViewGrid seems to be breaking regular scene view interaction after using the tilemap editor.
// If this is a built-in Unity Editor tool, then destroy the paintable scene view grid.
// Otherwise recreate it if needed.
if (ToolManager.activeToolType.Assembly == typeof(Editor).Assembly)
{
    DestroyImmediate(m_PaintableSceneViewGrid);
}
else if (m_PaintableSceneViewGrid == null)
{
    m_PaintableSceneViewGrid = CreateInstance<PaintableSceneViewGrid>();
    m_PaintableSceneViewGrid.hideFlags = HideFlags.HideAndDontSave;
}
