Instagram Live Display Issue

Hello, I need your help because when someone invites me to their Instagram live, the screen goes black on my side and I can only hear sound while I can see and hear the person who invited me perfectly.
Basically, when the screen splits to show both people live, my screen is black, etc.
And it bugs until I can't be heard anymore, etc.
It's quite problematic because I need this feature to communicate with people; I was invited to do a live music performance, etc.
If you could help me out.
I have the latest version of the app and I'm on a Huawei P30.
I've granted all permissions for the app, but it doesn't change anything.
When I'm called via a private call, it works well, you can see my face and everything.
But when it comes to a live, it causes issues.
The Android version is 10 and the EMUI version is 10.0.0.

Thank you.
