Repeat in playback not working

When trying to play score repeat not working. In playback option it says:
Invalid repeat structure detected. Fix to reenable repeats playback.
How to fix?

Seems like the repeat sign in bar 52 is going nowhere. That’s the reason I think.

Thx! That was the problem

I would replace that with a D.C. al Coda.
A D.C. in the first rep is rather unusual in my opinion.
