Since a few days, I get this error on updates for Microsoft apps, Movies & TV and Groove Music so far. The update will download and then throw the error, the apps also don't start anymore, they immediately crash. Non-Microsoft apps install and update fine, it's only Movies & TV and Groove. I'm guessing it's all Microsoft apps, but as long as no other apps get updated I can't check obviously.
What I've done so far: checked my C/Windows/AUInstallAgent folder, it's present. Checked my drives and RAM for errors, even did a 5 hour run of Prime95 to make absolutely sure my hardware is fine, no issues.
Any help would be appreciated, Movies & TV and Groove don't bother me, but if I'm right and sooner or later no Microsoft apps will work, it'd be a shame.
