I don’t know why sublime felt it necessary to open all 24000 files in the software suite that I’m a developer for but it did. Not really a problem because I found tabsextra which would let me close them all in one go without saving. But when I restarted sublime to install tabsextra apparently all 24000 files have been changed on the disk and it wants to know if want to reload each one individually.
I know it’s a meme but…

Go to Sublime’s data directory, and remove the following files:
That should be it.
Depending on your platform the data directory might be in %APPDATA%/Roaming or %APPDATA%/Local on Windows, or in Sublime’s installation directory on Windows if you’re using a portable installation, or in ~/Library/Application Support/Sublime Text 3 if you’re on macOS, or in $XDG_CONFIG_HOME/sublime-text-3 if you’re on linux.
Sublime Text doesn’t open a file unless you tell it to, my guess is the opening of all files was one by a plugin or a global find/replace. Resetting your session does seem like the best fix here unfortunately.
