From the looks of it, it seems like there's a conflict between secret rooms and simply jetpacks. I'm not a coder but I'd suggest deciding upon which is truly necessary and remove it and starting the game again.

I may be wrong but that's my basic diagnosis.

Looks like the Secret Rooms mod is trying to cast itself to an upgrade recipe to one of Simply Jetpack's Jetpacks, but it's failing to.
