Why would Instagram suddenly have a problem with IOS software and how would that be fixed?

Software update could stop an endless look big that keeps software running and causing it to overheat
Electronics heat up when the computer processing unit (cpu) is operating. The faster the cpu operates, the more inefficient it is, which produces heat. Phones also have a thermal resistor that can measure temperature. A software update could reduce the speed of the cpu when the phone reaches a certain temperature. This gives time for the phone to cool off through the metal enclosure
The phone overheats when the processor is asked to perform intensely. Instagram is just photos/videos, it shouldn’t be taxing the processor like a video game or 3D Lidar photo scanning would. It seems the overheating was due to an issue with background updates, so the new software update fixes that bug.
Step 1 : Blame the entire problem on one specific cause that isn’t too big and seems easily fixable.
Step 2 : Throttle the CPU so it generates less heat.
Step 3 : Announce the problem is solved hurray.
Step 4 : Actually fix the design issues and silently roll out a new model under the same marketing name.
Step 5 : People who bought the iPhone15 in the 3 first weeks are the kind that will come back to buy you a new phone in 6 to 12 months when the throttled faulty models die.

The answers here are a bit incomplete by being very software focused.
A software problem that caused the processor to be very active and generate a lot of heat then exposed a flaw in their hardware and phone design.
Most computers are designed such that their processing power is incapable of overheating, through better cooling matched for the heat generation and sophisticated performance throttling to reign in temperatures. For example, I can run my folding rig for literally years on end completely maxing out all cores on the CPU and GPU with the most intensive processing possible, and the hardware handles it just fine.
The root of this issue is that the thermal power output of the processor in that phone model is higher than the thermal dissipation of the phone. Apple may have done this anticipating high loads to come in bursts (which they do), and wanted to minimize size, use materials for aesthetic rather than heat dissipation, and pack in more short term/burst power than the phone should handle.
When an app or system activity runs constantly, it causes the processor to heat up (activity = heat). There seems to be an issue with something being allowed to run constantly with the new phone and operating system, so Apple has released a fix that is meant to prevent this. So the processor will no longer be in constant use and phone can stay cooler.
Software told phone to do something.
Phone did something.
Software didn’t tell phone to stop.
Phone kept doing “stuff” even if it didn’t to, or did not need to, or was no longer required to do the “stuff”
Again, software didn’t tell to phone CPU to stop.
Cpu and hardware constantly doing stuff = moving electricity ALOT = this causes some heat = phone did a LOT of stuff = this causes a LOT of heat.
Software update now tells phone to stop when it’s supposed to stop, and therefore phone doesn’t work as hard = no more heat.
Same reasons why Reboot/Restart fixes things. Cause reboot FORCES everything (well kinda everything) to STOP.
And that fixes stuff.
Same reasons high end games on mobile makes phone hot (cause a lot of things and stuff is happening in high end, high graphic setting, high calculation games)
Extra information:
Most desktop and laptop computers are designed not to overheat. They do this with heatsinks and fans. Desktops have real big fans, and laptops have small fans that spin fast. My desktop can go fast all day with no problem at all. It’s designed for that. My laptop can go fast all day and the only problem is that the fan is loud. That makes sense – the fan has to be small to fit in a laptop, so it has to spin fast and that makes it loud.
Phones don’t have any fans at all. But they still want to go fast when it’s important. They’re designed to go fast for a limited time, like when you press the screen to open the app, and rest most of the time. My phone *can’t* go fast all day or it gets quite hot. You easily notice this in some games – that’s just how those games work – they don’t have any ‘rest time’.
There’s no danger for the phone. When it starts getting too hot, it will slow down to a safe level and keep the heat at a safe level too. It won’t catch fire – unless it’s a Galaxy Note 7. However, it can get uncomfortable to hold, and the keeping the phone in fast mode makes it drain the battery faster, so it’s still a problem.
Phone is a grocery store. Software is a manager that deploys employees to do the work. It looks like the manager might have accidentally made an intern work 24/7 to clean something.
Eventually, the intern started burning out and screwing things up, which caused a problem like accidental fire or half-cleaned equipment, etc.
When you run really fast you get hot.
If you slow down you’ll be less hot.
The software update likely tells the phone to run a bit slower.
