I have the same issue (Windows 10) - I notice the path is repeated in the error:
C:\Users\<USER>\AppData\Local\Programs\drafft\C:\Users\<USER>\AppData\Local\Programs\drafft\resources\app.asar
i.e. 'C:\Users\<USER>\AppData\Local\Programs\drafft\' is repeated twice, which is invalid (if the error is accurate)...
Very much hoping this can be fixed!
