Of course. What you mention makes a lot of sense, and it could actually be something real going on with the chicken breasts. Let me explain:

Issue with the raw ingredient
What you describe as “spaghetti meat” or “woody breast” are quality defects in chicken meat that have become increasingly common due to intensive production systems.

Woody breast: the meat feels tough, fibrous, with a dry, almost “woody” texture.

Spaghetti meat: the fibers separate like threads, resulting in a soft and poorly cohesive texture.

These problems make the meat difficult to slice, stuff, or handle without it tearing — exactly what you’ve been experiencing with the Cordon Bleu.

How to check for it

Look: when cutting the breast, if you see loose fibers or uneven consistency, it’s likely affected.

Feel: if there are areas that are too hard or too soft, that’s also a sign.

Try a different brand or supplier: sometimes it comes down to the batch or the origin of the chicken. Buying from trusted butchers or going for free-range/organic chicken usually improves the texture a lot.

Possible recipe fixes
If you can’t change the meat, you can:

Pound it gently with a mallet (between plastic wrap) to even out the texture.

Slightly freeze it before butterflying, so it holds its shape and doesn’t tear as easily.

Wrap tightly in plastic film when rolling the Cordon Bleu, then chill before breading and frying.

In conclusion: it’s not that you’re doing anything wrong — most likely, you’re working with chicken breasts affected by modern muscular myopathies (very common in broiler chickens). Switching supplier or chicken type could make all the difference.
