The other day, I encountered the following issue: after exporting my UE5.4 project and attempting to run the .exe file, nothing happened. I also tried exporting in debugging mode to access the log files, which I’ve attached. My question is how to resolve this startup error. Unfortunately, I’m still a beginner in this area and don’t know where to start!
