Epic games and unreal engine Customer Care?!

The fact that Unreal‘s support is not on the phone ■■■■■■ me off!
I have epic games downloaded on my laptop, I am trying to download UNREAL. I had unreal downloaded and working last semester, this semester I open unreal and it crashes the game I started making. I look up online how to fix the issue, and it tells me to download Unreal’s new version 2.26. THE UPDATE NEVER LETS ME OPEN UNREAL!!! I went to computer experts and they couldn’t even help me. Yall need to fix this because this is midterms week! Ima need a response earlier than 6 hrs because i already have a missing assignment!
