Hey there @Friskymeth! Welcome to the community! Sorry to hear you’ve lost your player blueprint! If you’re using any form of source control, I’d recommend rolling back to a previous point. However you may be able to find a backup in the YourProject\Saved\Autosaves\
folder. If you do find the player’s BP there and intact, first I’ll recommend backing up your current version of your project, then replacing the 0kb playerBP asset with the version from the Autosaves folder then launch the project again. Let me know how it goes!
