The most crucial action made by Dr. David Bowman (Dave) is the deactivation and dismantling of the HAL 9000 computer.
This action is crucial because it resolves the immediate existential threat to Bowman and allows the mission to continue toward Jupiter, leading directly to the film's climax.
Bowman, having been locked out of the ship by the rogue artificial intelligence, makes the decision to sacrifice his protective space helmet in order to gain entry through the emergency airlock.
No one helps him.
Dave Bowman is entirely alone when he makes the decision to re-enter the Discovery One and carry out the deactivation. He performs the crucial action of disabling HAL solely based on his own will, survival instinct, and determination to complete the mission, overriding the lethal obstacles created by the computer.

While the HAL deactivation is the dramatic peak of the second act, the entry into the Monolith is the film's ultimate 'crucial action' regarding its theme of human evolution and the transformation into the Star Child.
The summary omits the crucial context (from the novel and implied in the film) that HAL's breakdown was caused by conflicting instructions from Mission Control regarding the mission's secrecy, which 'helped' cause the situation.
The Monolith acts as an external 'helper' or guide for humanity's progress, including Bowman's final transformation, which complicates the 'No one helps him' claim.
The most crucial action made by Dr. David Bowman is the deactivation of the HAL 9000 computer, which represents the triumph of human agency over a malfunctioning tool. Bowman performs this action entirely alone, as his co-pilot Frank Poole and the hibernating scientists have been killed by HAL, and Mission Control is out of contact. However, a second 'most crucial action' is Bowman's decision to enter the Monolith/Star Gate at Jupiter, which leads to the next stage of human evolution. In this latter action, the Monolith acts as a catalyst or 'helper' by facilitating his transformation into the Star Child.
