Strange cutting on the master for no reason

Hi
I have a strange problem and I want to know if somebody else has the same

I played my project starting with the play start button. The project includes 4-bars loops with 5 instruments on different tracks and 3 drum programs. the CPU never goes up to 40 %.
But for no reason, the sound cuts brutally after 1 minute and 20 seconds, but the sequence continues to play.
I have to stop the play and wait a few sec before the play starts the sequence again and the sound comes back.

Has anyone had the same problem?
I am out of a solution and tired of searching

thank you

nope.
project related issue?

have you tried resetting your preferences?

Might be related to polyphony, if the loops / instruments aren‘t cut off properly or have long silences.

To stop all sounds, press stop multiple times (double stop for choking audio, triple stop for PANIC / all MIDI NoteOff IIRC).
