Microsoft Store hangs on startup under W10 after Win-slop

W10 Home (EDIT1: non-English if that matters), Winslop inspect/apply, restart, an attempt to run Microsoft Store, Microsoft Store opens fully or partially and hangs, Microsoft Store's cpu usage 100% of one thread, dwm.exe 100% of one thread. Microsoft Store unusable!

EDIT2: This is a second time it happens for me (perhaps those W10s were upgrades from W7/W8). Any MSSTORE reset/reinstall won't help. Some setting made with WinSlop bricks Microsoft Store.

EDIT3: "restore" did not help, the MsStore is bricked :(
