Not Foundation, but sounds a bit like it. Galactic empire collapses because no one knows how the technology that powers it works anymore.

No it wasn’t Foundation. I don’t think it was from a very well-known author all I can remember about it is that and they had genetically engineered cats that glowed blue to detect radiation leakages.
The whole ship was designed so that people could forget how to operate it, and it wouldn’t really matter. Can’t really remember the justification for just not writing things down and keeping knowledge.
