It gets even more strange, Harm: your code runs without error under 
2.21.0. When I tried playing with the forced octaves (e.g. the c, in bar 
6), I could reliably trigger the error, although only for the octave 
down marks, not for octave up. It was repeatable up to bar 17 and never 
happened after that bar. I noticed that bar 17 had q1*3 and produced 2 
empty bars, so I changed bar 17to q1 q q which eliminated the bezier 
error in the whole snippet, including in bars where it was absolutely 
repeatable before that change.

I readily grant that I'm just poking a hornets' nest with a stick, but 
maybe it gives at least a work around for your project.

Cheers,
Colin
