Long story short, while trying to fix Store (stuck on circles loading screen forever) I ended up deleting the entire Microsoft.WindowsStore.somethingrandomalphanumeric inside my user AppData folder, which stopped the perpetual hang - by making Store not launch at all. I was hoping that deleting that folder would cause Store to reinitialize (like deleting the preference files in Mac OS *spit*), but obviously that is not the case. Is there a way to fix it? I tried converting my account to local and back, and resetting my computer causes a bsod loop then automatically restores.
