RCS Issues, Google Messages Glitch, Group Message Issues

The only thing that worked for me was to delete my Google account from my Android device and then sign back in. And remember, before you remove your Google account from your Android device, make sure that you have backed up everything. Go into your backup on your phone and make sure everything you care about is checked, especially if you want to save your RCS messages. After the backup, you're going to go into accounts area under setting and remove your account, and then you're going to add your Google account back in. Make sure you have backups of any two-factor authenticator app you have on your phone and make sure you know your Google password before doing so! I know it sounds like a pain, but that's the only thing that worked. And by the way, Google is the entity who told me to do this as I have Google one and have Google support that I'm able to contact.
