hinderer
One who impedes
A hinderer is someone or something that impedes progress or creates obstacles.
The word appears in contexts where someone actively slows or blocks another's efforts: He was more hinderer than helper on the project.
The term is uncommon, with obstacle, impediment, or simply "someone who hinders" more frequently used.
