A rodent chewing on wires. Vibration-induced chafing. Tin whiskers causing an intermittent short. There are many possibilities, those came to mind first.
But why does the pilot then comment that they are in the CUTTOF position and move it to RUN? A mechanical failure would have to also move the physical switch in the cockpit for the audio recording to make sence.
It amazes me that some people can ever make it out the door if they spend all their lives contemplating a series of increasingly unlikely possibilities.
We know that the switches physically moved from the run to the cutoff position because one of the pilots noted that they were in the wrong position. We know that they were moved back to the run position because they found in that position. I don't understand how a short could explain that - it really seems like someone would have had to physically move the switches.
It's not that rare, and there are institutional factors (such as seeking treatment for psychosis being career-ending for a pilot) that incentivize serious pilot mental health crises being untreated.
Both switches, at slightly different times? Seems pretty unlikely.

Serious question: why is it so difficult to fathom that a deranged pilot could decide to commit suicide by plane?
Not difficult, but can you close an investigation on that note without going over other possibilities?
What if there's another safety lesson to be learnt here?
The investigation isn’t closed. A preliminary report is usually required to be released within a few weeks of an incident.
To answer your question: because it is a very rare occurence.
It's not that rare, and there are institutional factors (such as seeking treatment for psychosis being career-ending for a pilot) that incentivize serious pilot mental health crises being untreated.
All commercial plane crashes are very rare occurrences.
