macOS TextEdit misbehaving after opening a binary mp4 file

Using Sequoia, I loaded an MP4 into textEdit because I was trying to find out if it had shellcode in it, and it has jammed up TextEdit I have to force Quit it this app repeatedly when I try and open it now in order to use macOS. To try and fix this, I looked in ~Library/Containers & ~Library/Preferences but there isn't anything I can find where it's keeping the files that are loading into TextEdit. What can I do to fix this app short of reinstalling macOS. I’m not even sure a reinstall on top would fix this if this is due to my user settings remembering this file what was previously open. Can I fix macOS and TextEdit hanging after this?
