its completely disappeared after swithcing from essentials tab to audio tab, tried resetting workspaces, updating to newest premiere pro version but nothing worked so far, edit still plays when i start playback??
I assume you are now in a custom workspace; it is neither Essentials nor Audio.
In any event, switch to an installed workspace (e.g. Editing), and if that doesn't work, reset the workspace by Window -> Workspaces -> Reset to Saved Layout.
The Timeline panel has more info than yours, even if there are no sequences open in it.
If nothing is working, close PR and create a new test project. If that doesn't work, reset preferences.
