Stability Issues

Hello,
I experience unnerving stability issues on Visual Scripting. I only have one 3D shape opened and I don't think I my sequencies are extremely complexes. I only have 50 or so basics operators, one loop, some ekl scripts and a 2D nesting operator.

Catia needs to "reload" the sequence editor at best or restart completely other times.

It can happen when I modify one thing or, more disturbing, when I add a new operator.

Is the problem my gear or the guy in front of it ?

Thanks.
