App Crash when clicked on Hard Problem

[Rajkarnikar-unish]

The app keeps crashing when I click on the number of hard problems solved by total hard problems. The reason it is crashing on my leetcode account is because I have 0 hard problems solved.

To Reproduce
Steps to reproduce the behavior:

1. Go to Profile Section
2. Click on Hard TextView in the Problem Section
3. Scroll down to Screenshots
4. See error

Expected behavior
When clicked on the Hard TextView on the problem, a snackbar should appear displaying the percentage of acceptance rate.
