After creation project is not fully recognized as Maven project

[simasch]

I use the IntelliJ Ultimate and have disabled the bundled Quarkus plugin

Then, I create a new Quarkus project.

As you can see in the screenshot below, the Maven icon is missing:

I also cannot activate it from the menu:

This means the project is not fully recognized as Maven project, for some reason.

If I reopen the project, the Maven icon will appear.
