My entire department has been having issues with Illustrator recently. Will work fine for an hour or two, but then slows to a crawl, takes ages to save, and eventually crashes.

We have issues opening files as well.

we have:
uninstalled, reinstalled
reset our preferences
Updated drivers
and
tried ctrl + alt +shft open to save a safe version.

nothing has worked. we can't even go back to previous versions because now we get the same issue with them.
