Whenever you encounter issues such as these, create an ouptput log doc (like the one you’ve provide) and use search term “error” and/or “summary” to locate the Warning/Error Summary. The next lines immediately after this will show you errors in your build that need to be addressed.
In this case it is pointing out the following (among others):
LogLinker:Warning: Can't find file '/Game/TopDownBP/TopDownOverview'
Failed to find object 'Class /Game/TopDownBP/TopDownOverview.TopDownOverview_C'
Found unparsable ini setting Windows.EditorPerProjectUserSettings:DetailCategories:PlayerUnitClass_C.Character Movement: Walking:0 for platform WindowsNoEditor, invalidating cook.
Failed to find object 'Object /Game/TopDownBP/TopDownOverview.TopDownOverview_C'
String Asset Reference '/Game/TopDownBP/TopDownOverview.TopDownOverview_C' was not found! (Referencer 'None')
Can't find file '/Game/Animations/CombatAnimations/EnforcementAnimation/PlayerAnimBP'
There are other issues listed after these, but these should be addressed first. Some of the issues can be fixed by right-clicking on the Contents folder in the Content Browser and selecting “Fix up redirectors in folder.” Others, you can find by running a map check for each level. Others you will need to open (The AnimBP, for instance) and identify and correct the error. Fixing these, then deleting the Intermediate and Saved folders from your Project Folder will help “clean up” your project.
*Last note: Again, I only listed the immediate issues. I recommend fixing these then repeating the process to identify further issues until there are no more errors or warnings under the Warning/Error Summary. That said, if you wind up with just a few warnings, sometimes you can get by with minor warnings left in your game even though this is not ideal.
