These verses also warn against adding to or taking away from the words of prophecy, which aligns instead of contradicting with Proverbs 30:6.
Revelation 22:18-19: For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:

Paul warns against a different gospel, reinforcing the idea of consistency and purity of message, similar to Proverbs 30:6 rather than contradicting it.

Paradox #1
Proverbs 30:6 warns against adding to God's words. A possible contradiction is that different people have interpreted and added to religious teachings over time, raising questions about which interpretations or additions, if any, are valid. This can lead to conflicting beliefs about what should be followed.
