The System.MissingMethodException exception usually happens when Godot breaks compatibility. In this case, the method Godot.FileAccess.StoreBuffer was changed in #78289 (4.4-dev6).

This means that your project or one of its dependencies were built against an older/newer version of the Godot bindings (the GodotSharp package). Make sure your C# project and all its dependencies are built against the same version of the Godot bindings, and that this version matches the version of the Godot editor you are using (presumably 4.4 beta 1).

You didn't provide a minimal reproduction project, only a code snippet that references undefined variables. This is not enough because, as explained above, the issue is not with the code you are using.
