I can confirm for this particular score. Not quite sure what the specific conditions are, but I couldn't manage to reproduce it from scratch in a couple of similar cases. The glitch is temporary - it fixes itself in the next relayout of the measure.

Somehow this seems related to #285141: Beam across a system break can disappear even if the specifics are different. But I don't think there are any other reports of this specific situation.

it happens at the beginning of a line or page when it has cross staff notation. when you change something then the beam disappears

Unfortunately it’s not that simple, as I said I tried and failed to reproduce this from scratch. There has to be some other variable here, but it’s not clear what. I thought it might be the tuplets, thought it might be the subbeams, thought it might be the grace notes, do perhaps there was a cross measure beam as well, but it doesn’t seem like any of these are it.
