Windows 10: Shell infastructure host using 75%+ of memory when using file explorer

I have my pictures and videos stored together and whenever I browse through the videos, after maybe 20 videos or so my PC will become very slow and it will for example fail to play whatever video I clicked on and will start playing the most recent video added to the folder. Then from there it will be incredibly slow for around 15 minutes, taking 1 or 2 minutes to load each video. And sometimes it will go back to normal quick speed another 2 minutes or so, but then will return to being incredibly slow. And when I check task manager performance, the Shell Infrastructure host is using 75-95% of memory I'm using a AMD Ryzen 5 3600 with 16GB of ram, a 500GB SSD which windows is installed on and 1TB HDD, so I feel as though this shouldn't be struggling to play videos from my files. I should state this doesn't happen normally when I'm using file explorer it's usually very fast. It's only when I repeatedly play videos that it slows down immensely, as I said it fails to play the correct video and picks the most recently added one and is incredibly slow from there. Any help would be greatly appreciated, I tried checking my HDD and SSD for updates but there were none, this has happened on many occasions so turning the PC on and off has no effect.

Explorer constantly paused by Shell Experience Host

I've installed all of the updates, and they haven't caused any change.

I ran the System Maintenance Troubleshooter as an administrator and it said, "No changes or updates were necessary."

I also followed all of the steps for the System File Checker tool and it didn't find any integrity violations.

I wonder if manually replacing the Shell Experience Host would be worth a try... Anyway, I appreciate the help.
