The wording simply says “a disintegrate spell”. It does not say what it has to be cast on or wether it continues to travel towards the real target afterwards. But the implication clearly is that you have to hit the wall. Thus, RAW, even with specific overriding general, you cannot target the wall because it is invisible (nothing in its spell description states otherwise) and you can’t target space behind the wall, as it is behind cover.
In order for the specific circumstance called out by the disintegrate spell description to be possible it requires a violation of the general case, yes. That is literally the point of the “specific overrides general” rule.
One of two things must be true for disintegrate to be able to destroy a wall of force:
1: The Wall is targetable by disintegrate.
2: Objects on the far side of the wall are targetable by disintegrate and the wall gets in the way.
For “specific overrides general” to hold a DM must rule that one of these is the case, otherwise the extremely specific interaction called out in the disintegrate spell description is impossible.
Of course as DM you can rule that this is not the case and disintegrate does not destroy a wall of force, such is the prerogative of a DM, but I am firmly of the opinion that such a ruling is not RAW.
“Specific overrides general” is RAW though, and the spell description of Wall of Force calls out that exact spell interaction as a way to destroy it.
