As with all releases, some showstopper bugs may pop up after the game's release.
There's no connection between the Update Aquatic and the Super Duper Graphics Pack. Worlds originally generated using the "Customized World" options can't be opened in 1.13.
Because of major texture pack changes in 1.13, a lot of block values have been updated.
To fix this, you will need to wait for the resource pack owner to update their resource packs to 1.13.
The Update Aquatic the latest update to Minecraft, and the first to be released across multiple Editions (Java, Windows 10, Xbox One, Switch, PS4) almost at the same time.
There are new mobs, new items, new blocks, new structures, new biomes, new game mechanics, and lots of water. The complete 1.13 changelog is on the Minecraft website, as well as the Minecraft Wiki.
