Could you try running the game through a Terminal and pasting the last 10 lines or so that get printed out after it crashes in here? This could help seeing what's wrong.
This is when no mods are installed in my game

This should get fixed in 0.4.2, seems like certain mods break the save file so the game just crashes.
For now you'll have to go to AppData > Roaming > FunkinCrew and move the file inside it to a backup folder, when the issue gets fixed you can replace the other file that gets created with the one you backed up
