Home Navigation button / gesture not responding while clicking.

Another problem I noticed is that while closing Chrome by clicking the navigate back button, the app stays in the home tab and doesn't close.

Also, for any app, on clicking the home button the app freezes with touch active for background app icons. That is, if I click Home button now, Samsung Members will freeze and if tap on the screen any app icon that might be placed at the location of my tap is opened through the frozen Samsung Members screen.

Request community to help me understand how to resolve the issue.
