Audio Segment not playing

Hello everyone. I hope I get help from here.
A segment of my audio track is refusing to play.
I was working on a podcast and after recording about 40 minutes of audio I tried to playback to here what I recorded and I noticed that about 30 minutes of the event where I had a pulse is not playing but the event after that is playing. All on the same track.
I am a longtime user of Cubase but I have never encountered

Hi and welcome to the forum,

I guess, you are talking about an Audio Event.

Isn’t it Muted by any chance?

Could you attach a screenshot, please?
