What is the name of the PC game (see description)?

I'm looking for a game that I played about 3 - 4 years ago, but I do not remember the name…

As description:

It is a (previously) free online game that you download (a luncher), you have a home island (flying island) and can get through a portal to the main island, there are dealers and stores. You can also enter dungeons to fight monsters, take loot, recipes and items, and building materials (to make your island). You can also earn money by selling loot and quest and get better swords etc. And buy recipes.

The whole game is nicely animated and the world is made up of many smaller blocks, you can also build together with others on an island. I think (!) That the game starts with "Q" and has a blue symbol as logo.

If you know which game that is, or you have a (serious) guess biite write it down below. But please do not write something like Minecraft, Fortnite, Roblox… Etc.

If you have played the game on Steam, you can look under your games

Ne was not on Steam, otherwise I would have done that.
