Videos not loading

a few days ago I recorded some of my volleyball matches on my phone so that I could look back on them later to review and look for clips.

there are 3 videos, 28:52, 28:28 and 11:47

at first, I spent a bit of time looking through each of them but as the day went on my phone started to become very slow. tons of packet loss and delay on everything, I then decided to reset my iPhone (an iPhone 13 that is fully up to date on IOS updates). then later as I went back the two longer videos were having an issue where they would not load, when I tapped on them to open them up it simply just held a loading sign, after a while it may stop loading and an exclamation mark may appear and sit in the corner, however, the more common issue was after about 15 seconds I would be kicked off the photo app and my phone would be frozen for a few seconds. the issue continued with the 3rd video soon after.

i have checked in my storage and these videos are taking up storage, they are the largest videos on my phone however previously I have recorded multiple hour-long videos of games (all on my phone at once) and never had these issues. i still have 100GB+ of storage free too.

i have already searched up for solutions and none have

Does anyone know of a solution to fix this issue?
