One of the most likely candidates for filter (and variant of our future) is not mentioned here. That is, technological progress will simply end much sooner than usually expected, without any catastrophic events. There is not a filter, but a solid wall on the way from current technology to dyson sphere and starship building.
I agree this is a possibility - a special subtype of the collapse. It seems unlikely to be a convergent enough high probability outcome that it could explain the fermi paradox.
I mean not collapse, but that there is an option that technologies necessary for interstellar flight and megascale engineering are either impossible in themselves or impossible to obtain for any civilization.
