Bought this light when we moved in May 2020. It worked fine for a while, but u recently noticed a bulb was burnt out. Or is it?

An electrical problem with the power going to the bulbs...a really weird one considering that those bulbs were almost certainly wired in parallel through the switch connected to the chain. Maybe power's feeding "backwards" through the one that appeared to be blown somehow?
Are all 3 bulbs the same? Is one led and others ole incandescent?
Some bulbs, as they fail might just glow less bright.
In reply to John Welsh :
They're all the same weird shaped led. I actually have the same light kit attached to a different fan in another room that's still holding up fine.
This had been going on for a while, I just finally got curious enough to make the clip.
I will add the fan that was there before was dead when we moved in. Like 1rpm on high with no noises and no lights dead. But so were most of the things the previous owners left us.
For some reason, I can't see my video in the first post, so I'm posting a different link here
Seems like that socket isn't getting power when the others do, and the bulb lights up when it's being back-fed by fan motor.
Im sure we have an electrical guy who can draw a schematic of what I just said.
I would try moving the bulbs around to see if that changes the behavior.
On edit: after listening with sound, it was clear that it was only a single cycle of the switch so I deleted that part.
It's the bulb itself. Something in the transformer I bet
Are those CFLs or LEDs?
If so, the ballast/power supply in the dead bulb has failed.
Yeah I was assuming they're incandescents. If they're LEDs, almost certainly the bulb itself (which includes power conversion hardware which is the culprit).
It does not take a lot of power to light off an LED bulb just a bit, there could be a voltage spike as the switch opens that is causing what you see. I would swap the bulbs around in the fixture to make sure the problem follows the bulb (if it doesn't then you have an internal wiring issue) and if that is the case replace the bad bulb.
Back when we were first converting cage free layer barns over to LED's you would see the odd bulb still on faintly just from voltage inducted into the wires from other loads, we would throw an incandescent bulb on each circuit just to pull that stray voltage down so the lights were off when they needed to be.
