If you're holding down the F key and nothing happens, your game has glitched. Reload the last save.

See if you remapped the key. Go to the key bindings and find out what it's assigned to, or restore default key mapping.

F is normally the melee key. Hit whatever your melee is assigned to.

The Normandy Crash Site DLC is the same way.

So it turn's out that I had assigned that action to another key and forgot about it. Thx for the help.

Not necessarily. That's only true when you're walking around. If you're in the hovercraft, it can still be F even if the melee key is reassigned. It's because they're in separate categories in the key bindings (ground controls and hover craft controls).

Just ran into this bug while playing the Legendary edition and this was the first entry on Google, so adding more info in case anyone else runs into this issue.

Basically the game prompt looks for the keybind for Melee (usually F on PC), which is the same keybind as Leave World, instead of the Leave World keybinding. However, if you remap the Melee keybind (mine is the Middle Mouse button), it is no longer the same as the Leave World keybind so it no longer works. You just have to check what your Leave World keybind is (it's at the very bottom of the Options > Key Bindings menu). Really though, the prompt should ask you to press whatever the Leave World keybind is, not Melee.
