Mac OS Messages Duplicating Sent Messages

After using a Messages App in Big Sur a few betas ago, the Messages app will send duplicates of every message. This only happens with specific conversations where the images App was previously used, and only happens on Big Sur Messages. Messages in iMessage on iOS and iPad OS send single messages, but show the previously sent duplicates.

Anyone experience this issue?
I am also experiencing this on the Big Sur beta sending SMS messages from my Mac. Every message is duplicated.
