I’m upgrading my project from 2022.3.41 to 6000.0.27. I installed the 2D packages which includes 2D animation, 2D Sprite, and others.The 2D Sprite package shows a check mark, but the other packages don’t. I suspect this is causing the new Unity editor to not display images correctly. How can I resolve this? Thanks in advance for your help!
