So, re-installing UEFN didn’t work, removing all files from the project that won’t load didn’t work either.
The solution I found is the next:
Open the EditorPerProjectUserSettings.ini
And search for the LastProjectFileName property (open the file with notepad)
Replace your current first-opening project to the one you would like, in this case “myprojectd”
This won’t let you get access to your project, but at least you can keep working with UEFN
