What makes you think it's a state actor and not regular malware, or even just a bug?

I once got pretty noided by my hard drive reporting to be empty once, thought I encountered a cryptolocker in progress. Proceeded to hard shut-down the PC and forensically inspect my HDD, turns out the HDD's USB firmware was starting to fail but my data was fine.

Do you have a CO detector in your living space and is it working? Do you have any reason to doubt your judgement here? Your theory seems far-fetched to me and the way you mention details raise my paranoia/mental illness/troll alarm.
