Is it possible for a planet to exist in a star's habitable zone yet still be uninhabitable due to its atmosphere?

The concept of a "habitable zone" around stars is crucial for understanding where life as we know it might exist beyond Earth. Typically, a planet is thought to be in the habitable zone if it's at a distance from its star where liquid water could be stable on the surface; however, being in this zone does not necessarily guarantee a planet's habitability. Various atmospheric conditions could make such a planet hostile to life. For example, a thick atmosphere rich in greenhouse gases might lead to extreme surface temperatures as seen on Venus, despite it being in the early edge of our solar system's habitable zone. Meticulous study of a planet's atmosphere, therefore, becomes crucial to assess its true potential for supporting life. This raises intriguing questions about other exoplanets discovered in similar zones and how their atmospheric compositions might also defy initial expectations.
