Popping/Vanishing physical object - Absolutely stumped

So update on trying to chase this issue. I am using a basic exponential function to apply the force for the drag right now. I noticed if I removed an extra multiplier it seemed to work better but still break. I have tried running it as a linear and even a s curve and it doesn’t fail. Is it possible I am attempting to add too much force? Anyways here is what the math looks like. Screenshot - 78ee7d0c64acf8dc41b828bfd1095a26 - Gyazo

It does sound / look that way.
