Could not load AddOn batch file

[Abion47]

In the log file, it says it's trying to launch the file in the folder "C:\Users\Abigail.DESKTOP-DD4K4BS\AppData\Roaming/SOMAModLauncher". In your screenshot of the error message, however, the path stops at "C:/Users/Abigail.Desktop". My guess then is that the launcher for some reason doesn't like the dash in your username. My suggestion (annoyingly enough) is to make a new account on your computer without a dash, or to be completely safe, with only letters and numbers (no symbols or spaces). Then try launching the game while logged into that user and see if you get the same error.
