I had a project started with version 5.0.0. With version 5.0.3, when I want to try a boot simulation the engine fails to start the .exe file, with error code 1. In addition, if you export the game, the .exe file does not start anyway. I tried to fix everything by creating a new project and bringing all the old assets to the Content folder. The game starts but the Open Level function does not work. Help me, I have been working with this project for 1 year…
