Bug in the tile palette if added a Gameobject with a ShadowCaster2d

[valentinbarral]

Hello,

I'm making a 2d tile-based platformer, and I wanted to use the Gameobject Brush to place the gameobjects on the grid. The problem appears when I try to place a Gameobject on the palette. Although the mechanism works fine, an incorrect texture appears in the palette, as if a sprite was missing. Still you can select the tile and paint it on the tilemap and the gameobject is placed correctly. You go into play mode and everything seems to work fine, but when you exit the editing screen is black and an error appears in console (I paste it after the video). However, if at this point you delete the gameobject from the palette, the error disappears automatically and the editor view works again. In the video below you can see the whole process.

I think the error is related to my objects including a ShadowCaster2d, and for some reason it crashes the editor. This only happens if the palette is visible when you press Play, if it is not the editor works correctly.

I am using 2d-extras version 2.2.0 and version 2021.1.7f1.

The error in console:

Thanks! We will check this out!

Hi, this looks like an issue with the URP package. We will need to fix this issue there. To get the fix, you will need to get a newer version of the URP package/update your Unity Editor version.
