Tell you what why don't I actually read the wiki
1. Electronics issue
2. turbo pump exploded - material science
3. aerodynamics
4. blew the plumbing when 6 engines were planned shut down at higher altitude. I'd argue that's a control issue.
The first launch did not fail due to that electronics issue though that was one of the first things to go wrong.
The propellant leak caused by Engine #2 issues is what caused the rocket to fail.
4.
Maybe if they had not shut them down that abruptly they could have avoided that particular failure mode.
All in all a pity that that program got cancelled, I still think it is one of the most beautiful rockets ever built.
