This is interesting because these are the words of John Baumgardner, who is a central figure in founding of the YEC notion of catastrophic plate tectonics and the Rate Project. Bold mine:
here here’s another question uh uh what challenges does uh this framework of catastrophic plate tectonics face uh that’s that’s an excellent question what are the what are the main challenges the main main problem issues with catastrophic plate tectonics uh uh I I will be rather bold and candid here it’s something I spoke I spoke on about a month ago at the creation research Society annual meeting in and uh uh it it it’s that uh catastrophic PL plate tectonics requires the hand of God actively involved in the in the physics of the flood and uh that that that presents a major problem for for some people it shouldn’t for for believers but it it even for for many Believers that’s a problem and in particular what I pointed out is that the cooling of all of today’s ocean lithosphere uh is simply impossible in the in the biblical uh in the biblical time frame uh you simply do not cool a slab of rock from near its near its melting point to the temperature that the oceanic slabs are today in just a few thousand years uh it’s certainly not a a single year and uh so in my very first paper on catastrophic plate tectonics in 1986 I pointed this out that that uh this is a problem for any any serious model for the flood and it is that of cooling the the ocean floor down uh uh within within the biblical time frame so uh to me it that uh I I mean I try to do my science carefully uh but when I hit something like that which is like a brick wall I I I I find myself saying this this looks like a point at which God intervened.

Note that it is just the frictional heat from tectonic movement being discussed, not even including the much more problematic accelerated nuclear decay.
