Swooshes like that definitely make for a possibility between shorting of multiple layers, best thing you can do right now is check your resistances as per this guide:
I think you should use a microscope to inspect that zone
I did the same on my first trim, but sanding that zone a little bit fixed the issue
Just need to try to sand to diagonally separate the layers and prevent shorts
I don't see any important signal in the top layer at that zone

So, I've cleaned it with a toothbrush and then alcohol next, and tested the resistances. The resistances are just a bit lower than what they should be. Is this bad?

In my 3 trims, the resistance values were different than the values on the post, even I saw two different values between 2 trims of the same board revision.
Just make sure they're not shorted or too close to it and try wiring voltages and video to test it
