This guide will walk you through the process of removing someone from your Facebook 'Blocked' list on both mobile and desktop versions.
Steps to follow

Tap on ☰. This icon can be found at the bottom right corner of the screen (iPhone) or at the top right corner (Android).

Scroll down and select Settings at the bottom of the menu.

Select Account Settings. This option appears at the top of the menu on iPhone or below the ☰ menu on Android.

Select Blocking
near the bottom of the screen with a red warning icon next to it.

Tap on Unblock next to the username. On this page, you will see a list of previously blocked users, and you can choose to unblock anyone.
