I have hired a remediation company to remove remnants of an old plastic mat, which turned out to have asbestos-containing black glue underneath. Because the company had trouble reaching all the way under the kitchen cabinets to remove these mat/glue remnants, they chose to apply a thick layer of AsbestGuard instead. Perhaps covering an area of 5-7 cm around the inner/outer walls throughout the entire kitchen. On the mat remnants with black glue, but also with a margin around, directly on the wooden planks. AsbestGuard is therefore also applied directly to the old wooden floor, above the crawl space.

Now to my question:
Could there be problems with AsbestGuard on this wooden floor? I will be laying paper felt and a new wooden floor directly on top. I'm mainly concerned about whether the AsbestGuard could create moisture problems. But maybe it's such a small area that it doesn't matter?!
What do you think?

Completely risk-free for several reasons,
The surface area is so small that it has no significance.
The primary moisture transport in a crawl space floor is downward, so if AsbestGuarden were to be unexpectedly diffusion-tight, it would only have a positive effect on the moisture transport in the floor.
Perhaps unnecessary information, but to clarify:
Moisture transport isn't driven by the difference in RH (relative humidity) in the air (as that would mean diffusion would go from the crawl space inwards).
Moisture transport is driven by the difference in actual water content in the air (often denoted as V or X) with the unit [g/m3] or [g/kg].
And the actual water content in the air is always higher indoors than outdoors due to generated additions from activities like showering, cooking, etc.
