Scene Builder not opening

Hello,

when I want to open an fxml file in Scene Builder in my project, I get the message "Failed to open the file in the Scene Builder. Download JavaFX". Pressing Download JavaFX doesn't change this. If I create a complete empty project and create a *fxml-File I can open this in Scene Builder.

In the idea.log I get tons of errors:

java.lang.UnsatisfiedLinkError: Native Library ...\.openjfx\cache\16\api-ms-win-core-util-l1-1-0.dll already loaded in another classloader

The project is a Maven/Spring  Boot/Java FX 17-Application. I use IntelliJ 2022.1.1 (Ultimate).

So did I made a misconfiguration or is this a bug?

bye

Roland
