I did a little bit of digging, and while I don't have an answer for what happened, I can confirm that the system only recorded one close vote from you, at 00:07:56 UTC on 4/18/21. This has the same timestamp as the review you performed in the Low Quality Posts queue$^{\dagger}$, meaning that your close vote from the queue was successful. Therefore, when you tried to vote to close the question earlier from the question page, it seems like something didn't go through. Is it possible that you clicked "cancel" rather than "close question" after choosing the close reason? The buttons are right next to each other, and I've definitely done that before.
At any rate, there were no effects on the post itself, which was obviously quickly closed in due course. I guess we can consider this case still open, if you'll pardon the pun.
$^{\dagger}$As a side note for other folks with mod privileges: The moderator timeline shows the queue task marked as "invalidated", but that label refers to the post's status in the queue, not your vote. The question was closed before other folks could review it, so the post was automatically removed from the queue at closure; therefore, for bookkeeping purposes, the review task is marked as "invalidated" in the history. The same label is applied to the uncompleted review in the First Posts queue, which nobody got to before the question was closed. This confused me for about five minutes before I found documentation on it (see that Meta SE post).
