This is maybe an obvious "yes," but is this tire toast? I've been having issues with tubes popping after changing over night, or shortly after riding. I've had five cases of my tube (3 new, 2 patched) popping shortly after install whether I rode it or not. I've inspected the rim tape, the inside of the tire, used plenty of talc, basically just followed any advice I could find about having an issue like this. Pumping it up and deflating it repeatedly to ensure it's seated in the tire, squeezing around to make sure the tire itself is seated properly, checking for any kind of bulges. No matter what I keep getting popped tubes within a day of replacing. Until! The last new tube I installed seemed to hold up for whatever reason.
Then today I went to inspect it, to make sure everything looked fine before finally braving a ride, and I noticed a weird sort of stretch/seam line running the circumference of the tire. The other matching tire has no such stretch, but there is a seam there. It's as if the seam sort of stretched open or something.
Does that indicate this tire is toast / I should get a new one / that was likely the issue? Again, I know it's probably obvious, but I've just gotten so frustrated trying to troubleshoot and pin this down again and again that I'm second guessing myself.
Maybe obvious, but is this tire dead/done for?

I wouldn’t risk it, it appears that the sidewall is failing, maybe the bead. You could use this opportunity to upgrade to a better tire. If you want something reliable, a Continental Contact Plus City tire (if they have your size) will serve you well. It’s a little expensive though. There are cheaper alternatives but I’d stick with the big companies.
The first thing that comes to mind with your tire is damage from riding on very low pressures. Do you know what pressure you run, and what pressure the tire is rated for (it should say). Tires should be pumped up every 1 – 2 weeks, and checked before every ride.
It´s hard to tell from the video but if it´s stretched or it´s been rubbing against something… in case of doubt just throw it away.
I’d double check why does that happen on that specific area. Is it a dynamo? Is it rubbing against a fender? The part of the thread that should really wear out looks just fine, but this… not so much.
If there’s no visible threads, I don’t think it’s a big risk. But it’s close to done and I’d replace it to be safe.
Unless the thread is showing, it should be ok. As the first response says, figure out what is wearing down the tyre and try to sort that out, it will save a repeat performance.
Looks like motion generator bicycle light, generator wheel wear on the sidewall? If the generator is going to continue to be used, fit a heavier tyre?
