Hello there @thristy_ares!

The error you are getting has been encountered a few times through the community, and tackled in a number of ways. Here are solutions that can be tested for your scenario:

  1. Please try deleting the intermediate, config, and saved folders from your affected project, then re-opening it (backup the folders in question, just in case). Certain settings may be reverted by this action, as the map used.

  2. Change two lines in DefaultEngine.ini, in the Config Folder:

[/Script/EngineSettings.GameMapsSettings]
EditorStartupMap=
GameDefaultMap=
  1. Edit the FPS component location in DefaultEngine.ini to the right location:

EditorStartupMap=/Game/FirstPerson/Maps/FirstPersonMap.FirstPersonMap
to
EditorStartupMap=/Game/cw_FPS/FirstPerson/Maps/FirstPersonMap.FirstPersonMap

  1. Change the following values, then re-build:

Engine/Source/Runtime/Engine/Private/Animation/AttributeTypes.cpp
EDelayedRegisterRunPhase::ObjectSystemReady => EDelayedRegisterRunPhase::PreObjectSystemReady
