I don't know if Justice League is a good example. They could have thrown the Teen Titans and Justice Society in that movie, yet it still would have had to pay for the sins of people not liking BvS.
Three things have to go right for this movie just to have a chance at success:
1. The final stretch of marketing in the next 3 weeks reaches enough of the GA to put in on their radar
2. Enough people need to be in search of a non-blockbuster, light breezy family film they can take their kids to
3. The word of mouth needs to be stellar.
Why did anyone seriously think that this was going to be PG-13? Especially after the first one still managed to get a PG rating despite being a bit more mature than your average family film.
DeSantis has all the charisma of a paper bag, his political instincts have proven to be lacking, and there's little about him that people outside of far right crazies in FL find appealing. We should still take him seriously, but he's not invincible.
That's why I don't see it collapsing like Lightyear did. Minions 2 stole all the oxygen in the room and delivered what families wanted from an animated Summer movie. Ruby Gillman could surprise, but that has even less awareness than Elemental does now.
