Got it compiled and running.
Question: are you building the project from your IDE or just running the uproject file?
Because if I try to run the project without the proper compile I get your error, once I compile it runs fine.
Remember to right click the uproject and Generate Visual Studio Files.
Here is the base project
playfabtest.zip (2.2 MB)
Right click the uproject file
- chose Switch Unreal Engine version
- pick your source version of 5.3.2
- on clicking ok it should generate the project.
Run the project solution to open your IDE
- Pick Development Editor, Win64
- Make sure the project is set as default (in this case playfabtest), it should be in bold
- Compile and run
