SOS postprocessing slower with newer versions of Yalmip/Matlab

I am running the command

[sol,msol,Bsol,residual]=solvesos(Constr,[],sdpsettings('sos.model',1,'sos.postprocess',1,'

sos.numblkdg',1e-12,'solver','mosek', ...

On my desktop I have Matlab R2025b with Yalmip R20250626

While solving the problem with Mosek is fast, Yalmip spend very long time with the

postprocessing. This is strange, since when I run the same code on my laptop with

Matlab R2021A and an older version of Yalmip (apparently R20230622) the postprocessing

runs much faster.

My desktop is significantly more powerful than the laptop, Mosek runs almost three times

faster on the desktop.

Is there any explanation for the slow postprocessing - and is there anything that can be

done about it?

You would have to supply a minimal reproducible example

or profile it and see if there is any specific part which stands out as excessively slow
