Adobe Animate 2019 not opening

Whenever I try to open Adobe Animate, it just doesn’t work. It gets on “Loading document types,” and the program immediately closes itself. I’ve already tried replacing the DLL file, but that just caused a new problem — it gave me two error boxes, then Animate would open for a couple of seconds before crashing again. I’ve also tried resetting preferences. I really don’t want to update to a newer version, so I’m kind of stuck.
