Thank you. The crash says that SecurityCraft tried to access code that it cannot actually access. The weird part about this is that we specifically modify that code to make it accessible. I am unsure what may be the cause of this, and I cannot reproduce it either. Try to see if this error still happens after removing canary, starlight, and rubidium (they make the most extensive changes). Otherwise, perhaps redownloading SecurityCraft may do the trick. In the next version of SecurityCraft, there will be a change regarding this, but I have no idea if that will fix this issue. I'll make the change purely based on a weak suspicion.
