Nope. I read it. The language of the 14th doesn't require an impeachment or other formal conviction to apply. The fact that Trump was successfully impeached for inciting an insurrection is enough. The Senate's failure to execute its duty does not erase reality.
At this time, on this topic, I am not concerned with what makes for interesting conservation. I am interested in bringing attention to the ongoing Constitutional crisis of Trump's tentative second term.
Neither of those facts preclude the application of the 14th. The barrier is whether or not someone holding public office, having taken an oath to uphold the Constitution, breaks that oath via insurrection against the same. It does not matter that Trump was not punished. The acquittal does not erase the reality of the past: it is a dismissal of immediate consequences. Nothing more.
The fact that Congress acknowledged the reality of January 6th is more than enough for the 14th to apply.
