dude, why in the world are you on Insider? mobile is not something you should have Insider on if you all ready have win10. Your production build is fine. I run my 950xl stock: it works100% all the time no complaints. My 640xl, however is on Insider. 640 came with win8.1 so thats why i ran Insider. Last update, i ran into the same problem as you after having a previously stable build. Im always having issues and complaints with my 640xl. My suggestion, roll back production. Im a hard core user. Excel spreadsheets, programme strings, photo editing, PowerPoint presentations, email, continuum, bluetooth keyboards, and active precision stylus - all on production build. YOU DONT NEED INSIDER!
