[Error] The given key 'System.Action' was not present in the dictionary.

[xys20071111]

I am trying to install BexInEx into a Unity game, and got an error:
Failed to generate Il2Cpp interop assemblies: System.Collections.Generic.KeyNotFoundException: The given key 'System.Action' was not present in the dictionary.

Here is the full log:

LogOutput.log

The log said this error was from Il2CppInterop, and I don't know what happened.
