these are the errors i am getting. i tried everything but decided to make it a different post because i know exactly what caused it now.

Using a file explorer go to the directory of your project where the offending file was. The meta file for it will be there. All Meta files reside next to their related files (they have pretty much the same name).
You can jump to location by right clicking a file in Project Manager and selecting Show In Explorer.
The file is still being referenced in the project. Deleting the meta files may help unless you’ve hardcoded the reference.
You really need to start using Google to your advantage! It sometimes takes way longer to get a good response on here than it does to find the answer yourself.
Instead of asking “How do I do that?”, jam it sideways into the Google box!
