JavaScript certification exam

Hello,

I successfully got my exam token, but when I pressed the Open Exam Environment Application button, the Exam Environment application briefly opened and then disappeared.

I downloaded the latest version of the app (Exam.Environment_2.0.2_amd64.AppImage), extracted it to a separate folder, and tried to execute it from the command line, but the app failed with:
“Could not create default EGL display: EGL_BAD_PARAMETER. Aborting…”

Please help me start the app so I can take the certification exam.
Thank you.
