Error Message while reviewing cards

A message that I posted below pops up when I click on “show answer” for some cards while reviewing. It crashes the app and I cannot move forward with other cards. I am stuck and have tried everything I was told online to do. What should I do now?

Do you have any scheduling-related add-ons installed? if so, maybe try disabling them: When problems occur - Frequently Asked Questions

Can you reproduce the problem after enabling the v3 scheduler?
