Playback stops in certain instruments after a certain measure // Note performer

I am working on a long multi-flow project which does involve copying and pasting a lot of material from XML files (kind of messy). But I am having this weird problem: after a certain point in the piece JUST the cello and bass are unable to play back. I’ve tried re-applying in the Playback Template, Independent Voice Playback is not enabled, and they both work before this point. Any help?

Can you cut the project down to the smallest chunk that still reproduces the problem, and attach it here?

A reminder about how best to ask for help effectively on the forum:

In the affected players, do you have any trills (specifically at the point in the piece which you referred to) where the Start speed and End speed properties have been changed from default settings? In September 2023 I contributed to a post after discovering that certain combinations of a trill’s Start speed and End speed properties can cause playback to be adversely affected.
