is it expected to get this error at the end of running phpcs?

and this error at the end of running csfixer

[LadySolveig]

No, absolutely not an expected result.
I have tried to replicate your issue but unfortunately I can't recreate it at the moment.

I have seen you run it directly on Windows.
Since I usually use Linux, I have now installed php 8.3 and composer directly on Windows.

But for me it runs without errors here too.

composer run phpcs

composer run csfixer

Is your IDE or your Git client possibly doing something with the line endings?
