No, but the issue was one where he believed giving the Royal Assent would be in violation of his Coronation Oath. It was made clear that if it had passed Parliament, that was not the case, because the Lords Spiritual had exercised the powers of the Church to influence the law such that they existed.
You speak only of the superficial legal limits on the Queen, not her actual real-world powers. In fact, the Queen has massive legal power simply by her deciding to argue that whatever she wants to do is, somehow, a constitutional issue. She literally has teams of attorneys who could argue such things at the drop of a hat - and of course, she has the wealth necessary to pursue anything she wants to pursue. but she doesn’t have to, because she does her arguing behind the scenes.
As for that wealth, it is more than considerable. in fact, it is so extreme that just by moving it around she can punish or reward any political faction she wants, and thereby apply enormous pressure to achieve political ends.
In the real world, what happens in Great Britain is exactly what the Queen wants to happen. The democracy there is just a cover story to pacify the people. The same dynamics are in place all over the world, including America, Australia, Europ, China, Russia, japan and everywhere else. Theses places might not have an acknowledged royal, but the global system of privilege and power is quite unified, and operates under the radar of the general public - but not as far under as people believe.
None of this is conspiracy theory, but straightforward economics. When you are talking about people and families, in GB and around the world, worth hundreds of billions of dollars, to subtract extreme political and legal influence from their financial dealings is simply naivete’.
