The quest will not give you a reward

How it happened: I had 297 people already counted and highlighted, and when I started a new game, I completed the list and got 300 out of 300. However, my game crashed during a match, and when I went back into the game, I saw that I had 300 out of 300, but I couldn't get my desired reward because of the game's error. No matter how many new matches I started, the progress bar didn't change.

I request that the reward be issued to my account in any other way, as I have fulfilled all the conditions of the task.
