Black screen when transmitting

[Luzbel]

When transmitting the screen everything works correctly, but when I want to transmit a game on a specific screen, it appears black and I have tried countless solutions and I still cannot find a solution. Thank you

The log file you linked has no streaming attempt on it and it's needed.
Anyway, make sure you are respecting the streaming service settings. Check on the streaming service support/help the max settings they allow.
