Man crushed diving Tidenham’s - Gloucestershire, UK

He died after sustaining a gas embolism and pulmonary barometric trauma.

Yeah that basically tells us he died either from decompression sickness(from that hour of deco obligation he'd skipped, and ascending too fast), or from holding his breath at some point during the ascent and having a lung rupture, or both.

Plugged his dive into iDeco and got a very doable dive (albeit pointless).
He was found 20 minutes after departure, so a total dive time of max 20 minutes to a depth of around 230 ft. Assuming a descent at 60 ft/min, he gets there in 4. One minute to turn around, normal ascent at 30 ft/min to 50 ft depth, then 10 ft/min to 20 ft depth. Once at 20, a 3 minute stop followed by a 4 minute stop at 10, then done. Total dive time 20 minutes, less than 80 cuft gas needed.
Of course, all that assumes proper control of all dive aspects.
I don’t get where is his one hour of deco coming if this was his first dive.

It wasn't. Read the article. He'd completed one dive, then borrowed a tank to go solo on a second dive.

Specifically, the update article: Diver died after rapid ascent from 71m

EDIT sidenote: We can't assume he dived a planned profile to 71m and did it by the book, especially since he wasn't qualified to go beyond 40m. It's just as likely that he droped down in 4 minutes, stayed for 14, and did a 2 minute out of air emergency ascent, especially given his barotrauma injuries.

Instructor Alexander Fox said that Jurasz had completed his Tec 40 qualification, permitting him to dive to 40m.He told the court: "On this day he had exceeded his competence levels. He was diving solo, which was not permitted at that depth. He missed one hour of decompression by coming up so fast."

He added that Jurasz was overweighted and had dived with his equipment set at “extreme levels”.

Gloucestershire police reported that its investigations had shown no third-party involvement or suspicious circumstances.

Jurasz “was not qualified to do a solo dive but he made the decision to do that,” summed up Coroner Katie Skerrett. “The reason for his uncontrolled ascent is not entirely clear. It may have been caused by how his equipment was set up.

"He was a qualified diver but he had exceeded the limits of his certification. It was a tragic accident involving a 28-year-old man doing what he enjoyed doing when he made a fatal error."
