Episode is released, but no valid sources!

[ashiq2002]

I'm experiencing this issue whenever I try to play any anime. The same error appears every time:

Specified quality not found, defaulting to best.
Episode is released, but no valid sources!

I've tried multiple anime titles, but the issue persists for all of them. Could you please help me figure out what's causing this?
