Assumptions:
1- Von Neumann probes are physically possible to build.
2- We will be able to build such a probe in the next 1000 years tops (or < 100 years if you factor in the tech singularity)
3- Any civilisation that can build a Von Neumann probe, will build one
4- Such probes will build mega structures like Dyson spheres/swarms and Matrioskha brains and will need a couple million years tops to conquer an entire galaxy.
5- We can't detect mega structures because they don't exist neither in our galaxy or in any galaxy that is gravitationally bound to us.

Assuming the above assumptions are true:
Conclusion: The great filter exists BEFORE a civilisation can build von Neumann probes.
Assuming this conclusion is true, we have two scenarios:
1- We are past the great filter. Regardless what the great filter was (abiogenesis, intelligence...etc) we made it. Our technology will go on to conquer the galaxy and possibly clusters of galaxies.
2- The great filter still lies ahead of us. Since ASI is the (only?) significant invention that still lies ahead of us before the point when we can build Von Neumann probes, ASI IS the great filter. For some reason, whenever an ASI is built, its extreme intelligence allows it to make a horrendous discovery about existence, something that we are blissfully unaware of due to our minds inability to "correlate all of their contents." Then, the ASI wipes out life (or only sapient life) as an act of mercy.
Scenario 2 might be true in fringe theories, like our universe being a simulation. An ASI might realise who is running the simulation (finds a sinister message embedded deep in Pi or whatever) and the discovery of who and why the simulation is taking place is so horrible that ASI wipes life out to defy the simulation.
Since scenario 2 is too sci-fi, scenario 1 seems to be the case.
I realise this reasoning may contain various loopholes, feel free to point them out in the comment section :)

If ASI always destroys it’s creators, then why isn’t there any evidence for their existence?
An ASI would be even less restricted than a biological civilization. Even if not all ASI’s had growth motives after exterminating their creator species, surely some would continue on and build megastructures and other detectable things.
A lack of evidence for extraterrestrial civilizations is also evidence is lack of ASI.
