Setting up character - tutorial: InvalidOperationException: System.InvalidOperationException on startup

[breakpoint-git]

Trying to set-up Tutorial project. (Step 2. https://github.com/Unity-Technologies/rival-documentation/blob/master/Tutorial/tutorial-characterhits.md) Unity version (2022.2.1f1, 3D/UPD template, Mac M1 silicon)

If to ignore error, character seems to be working fine. If to use Tutorial folder to set up the project, seems to be working fine as well. What Im doing wrong with manual setup?

Exception stacktrace:
InvalidOperationException: System.InvalidOperationException: GetSingleton<{0}>() requires that exactly one {1} exist that match this query, but there are {2}.
This Exception was thrown from a function compiled with Burst, which has limited exception support.
