What to do if sticky on 5 shift presses does not turn off in Windows 10?

Question

Windows

Good evening. It costs Windows 10, the latest updates are also worth it.
I press shift 5 times. A window pops up about sticky keys. I click on "disable this combination ...".
I uncheck "enable sticky keys..." "press shift 5 times...". The checkbox has been removed.
Reboot. I press shift 5 times. A window pops up about sticky keys. I click on ..... The tick is in place.
Where to look? How to uncheck this box once and for all, and not just until the reboot?

Disable Sticky Keys in Accessibility settings
