Synced Photos have reverted to old edits

Hi! Until last night I was happily running Lightroom Classic 13.5. I didn't realize it was several versions old because it didn't auto update. Anyway, I try to export (had exported earlier in the day with no issue) and I get an error. I close down the program and do a system reboot. Lightroom won't respond now or even open. I update and upgrade my catalog, now 90% of my edits are gone. Revereted back to 0, which is older than the last sync. I've tried redownloading the old version, but it still won't open. I've tried using old backup catalogs and the edits still aren't there. The cloud now has the wrong edits. Is there anyway to get them back or have I lost an enitre week's worth of work?
