Can you assess the problem?

What, with my browser or the accident?

lol

The T-6 passed 90 deg (and even earlier) with his nose below the horizon.
He could have rolled back and saved it at that point, but he continued
around in the now awkward position of having to prevent further altitude
loss with excessive neg G which slowed him considerably and further skewed
the airplane's. The exit half was a classic dish. Everybody does 'em
sometimes.... Trick is to recognise a roll that's going to produce one
early enough to abandon it. This guy didn't.

I later saw your post equipment failu

What I see is: first half of roll looks fine; but - as he hits the
wings level inverted position, the nose is starting to drop. At this
point of the roll, he should be pushing. But he's starting to pull,
then he pulls some more as he goes through the 3rd quarter of the
roll, causing it to turn 90 degrees and fly into the ground. Only
thing that can make it turn like that is up elevator. Also, I don't
see any top rudder (right) which would have helped hold the nose up.
Basically, the same control movements would produce a 90 degree
rolling turn, inverted to upright, outside roll. I've done lots of
these on purpose and its really hard not to lose altitude. Sadly, he
didn't have any altitude availble to lose.

Just back pressure coming off the backside of the roll wouldn't have
yawed him in like that. Back pressure held in through the second knife
edge would have TURNED him in on his wingtip. He literally yawed himself
sideways coming off the back side and hit flat. I'm guessing he held in
the left (top) rudder and never made the rudder switch through inverted
then let it dish out with the now bottom rudder yawing him off the roll
axis as he came on through knife edge on the way down. Looked to me like
a classic mis-application of controls starting at inverted.

What is the deal with the first crash shown in this video? Overstressed the
aircraft and it came apart? Very strange.

Can't access it at the moment. Is it the one where the Partenavia loses
both wings at the same time?
There was a reference to an accident report in which th evideo was analised
and the airplane was estimated to be traveling at 220 kts, 25 over red
line, and the rate of rotation would have given a loading of over 8. Plenty
to pull most airplanes apart instantly.

No it is an F14 doing a high speed pass just above the deck, then it banks
and a just explodes. It is kind if surreal like a Hollywood plane crash.

The airplane just blew up. As I remember the engine came apart. This
was on one of the Discovery Channel programs where they spent a bunch of
time on a carrier.

Catastrophic uncontained engine failure, is what I remember about that
clip.
