I am in the same boat with the same phone. I was on the insider fast ring with everything working just fine. I downloaded Garmin Connect app which kept crashing. I wanted to see if it was the phone so I reset and restored the phone. The Garmin application turns out to be poorly written. When I got my phone up and running again, my MMS/group messages weren't working anymore.
I reset the phone again but no luck. I then used the windows recovery tool and it rolled back to 8.1. MMS started working again but only as long as I stayed on 8.1. I upgraded to 10 using the normal upgrade path and it once again broke my MMS. A newer Windows 10 build came to the fast ring so I switched back to the fast ring, hoping it would fix the issue. It did not.
There is something wrong with the last few builds. Very irritating

If you are on the Insider preview, why don't you report the issue through the Insider's feedback app?

I have reported it numerous times on the insider app. I'm waiting for that fix and was hoping someone here might have a workaround.
