I have no idea what caused this...How do I fix it?

You have your Zotero data directory stored in cloud storage folder, which you
should never do
, since it's very likely to corrupt your database.
You should close Zotero and immediately move it out of there, and then try
restoring from a backup
(likely either one of the zotero.sqlite.* files in your data directory or, if you have version history for the cloud storage files, an earlier version of the main database — you should check database integrity from the Advanced → Files and Folders pane of the Zotero preferences to see if a given database is corrupted).
