And my advice will not benefit you - although I wished to (11:34)

﴿وَلَا يَنفَعُكُمْ نُصْحِي إِنْ أَرَدتُّ أَنْ أَنصَحَ لَكُمْ إِن كَانَ اللَّهُ يُرِيدُ أَن يُغْوِيَكُمْ ۚ هُوَ رَبُّكُمْ وَإِلَيْهِ تُرْجَعُونَ﴾
[ هود: 34]

11:34 And my advice will not benefit you - although I wished to advise you - If Allah should intend to put you in error. He is your Lord, and to Him you will be returned."

Noah told them that his advice and counsel would not benefit them if Allah willed that they be led astray from the right path, and if He willed to leave them without guidance because of their stubbornness.
He was their Lord and it was He Who had control over their lives, so He would lead them astray if He willed; and to Him alone they would be returned on the Day of Judgement, when they would be repaid for their actions.

"And my advice will not profit you, even if I wish to give you good counsel, if Allah's Will is to keep you astray. He is your Lord! and to Him you shall return."
