I’m not 100% sure what’s happening just by looking at your screenshots. Could be the tilemap is at the wrong z position, could be something else. Your scene is very simple, and Unity tends to work well out of the box, so something has to be messed up somewhere. We could keep asking for information for another few days, but the fastest thing would be to zip your project and link it here. I don’t mind downloading it and having a look.
Google drive is the easiest hosting site to use in my opinion.
Also, in the future, please use code tags: Using code tags properly
It wasn’t the best response here; KaiDevX is obviously very new and likely won’t absorb all that information, but saying he’s spamming and gatekeeping is a bit overkill. His post contains a ton of useful information on how to debug, which is exactly what KaiDevX needs to do here. Kurt-Dekker is one the most active users on the forums, he’s helped many, many people, and has provided a ton of useful information. I often link to his posts when I see people with the same basic questions (how to fix NullReferenceException for example).
