Hey, I'm trying to work on this for day 6 but Unity cant open it. It looks like its looking for a package on the Desktop "Desktop/Unity/ScriptPackages/com.unity.2d.tilemap.extras".

So it turns out the missing package wasn't what was causing the problem. From what I can make out from the crash logs Unity is crashing because of something to do with being unable to find URP shaders. But its getting late for me so I'm giving up on it for now, hopefully someone else will continue this for day 6.
