Google Messages Won't Send MMS Messages or Pictures

So for the past week, my Google Messages app has been notifying me in app that a MMS (group message or picture message) did not send. It keeps asking me to tap it to resend. I looked at the message details. I am receiving an "Error Code 128". I have not been able to find any information on this.

Furthermore, people ARE in fact still receiving my messages. Also, when using the default/built in messaging app, it does not display an error or concern the message was not sent.

Is anyone else...
