PKHeX won't start, can someone help?

Sorry if this is the wrong tag or smth, but PKHeX isn't starting anymore. Yesterday it loaded once, let me edit a save (it was a Z-A save if that changes anything), and then wouldn't load anymore when I tried to open it again later. Even if I delete and reinstall it won't start.

Check to see if it is running in Task Manager.
