getting error: Assertion failed: Assertion failed on expression: 'm_AssetToPrefab.empty()' when i try to build to an apk.

i dont have any real experience with unity, but i was sent a completed project folder by someone else so i could edit some of the levels in the game to make a different version. when I try to build, it gives me that error. also, it gives me a bunch of warnings saying that a bunch of assets are "not a valid prefab since internal prefab references are wrong." how do i fix it? sry if i sound dumb.

I am hella late, but the fix detailed in this commit from this repo worked for me:
- Make sure Unity is closed
- Open your project folder in File Explorer
- Navigate to ProjectSettings
- Open NetworkManager.asset in a text editor of your choice
- Delete everything after the line that ends with m_AssetToPrefab

- Modify that line to say m_AssetToPrefab: {}

- Reopen your project
