I ran into a similar issue when I added it whilst playing one of the early 1.22 RCs. I had to delete the folder for it in either AppData\Roaming\VintagestoryData\ModData or AppData\Roaming\VintagestoryData\ModConfig to stop the crash in additional to removing it from AppData\Roaming\VintagestoryData\Mods. You should be able to update it to version 4.0.0 too as LadyWYT noted. That should update any additional configuration files that are causing the crash.
