Are you asking because you had [recent?] changes to your collection (edits, review history) that were only on AnkiWeb and had never been synced to desktop?
If so, I can restore the last server-side backup to your AnkiWeb account, but you don’t get to pick a date or time. That last backup was made a little over 24h ago – click for time localized to your time zone. Please confirm if you want me to restore that version.
You will need to choose download from AnkiWeb on your next sync, which will overwrite everything in your local collection. Before you sync, make sure you have your local collection preserved, so you can merge that in after syncing. Syncing with AnkiWeb - Anki Manual
