Hello! I am a high school English teacher trying to give my final exam in Canvas using lockdown browser. I used New Quizzes to create the exam. When I go to my lockdown browser settings to require it be used to take the final, it simply loads forever. The attached screenshot is what I see.

It allows me to enable lockdown browser for another similar test I wrote with New Quizzes in the past. I can't figure out what's going on.
