VST instruments choke

I have this project that when I open it, there are 2 instruments that always “choke” when I first play it. What I mean is on the first note, the sound will trigger but immediately stop (they’re all long notes), but the 2nd note will play fine. If I replay the project, it will play fine. It’s like it doesn’t buffer or something. And it’s always the same 2 instruments: a choir mmm and a double bass legato sustain. All other instruments play perfectly. And it is only in this one project. The same instruments work fine in other projects. Has anyone encountered this before? It doesn’t bug me that much, it’s just annoying.

Hi,

Increase Buffer Size, please?
