I recently setup a new Spring Boot project using Maven, Java 21 and Vaadin 14.10.9. I use IntelliJ as my IDE. Because I am using Vaadin, I installed the "Vaadin Designer" pluging. When I try to open the project without this plugin enabled, everything works fine. However, as soon as I enable this plugin my project always gets stuck on "scanning files to index", seemingly making no progress (for several hours). This looks as follows:
Note that neither progress bar, be it the one in the middle or at the bottom, shows any sign of progress. They do have a small animation as if something is happening though. When I press 'cancel', IntelliJ continues as normal and I can run the program as usual. However, it does complain about installing several npm libraries that are already installed.
The last few entries of the idea.log file look as follows while the indexing is stuck:

I have already tried:
- Deleting my .idea folder
- Invalidating Cache
- Waiting for several hours
Note that I have zScaler installed, for what it matters.
What could cause this issue and how would I go about resolving it?
in idea.log, there is an error message about "java.lang.Throwable: AWT events are not allowed inside write action: java.awt.event.InvocationEvent[INVOCATION_DEFAULT,runnable=javax.swing.RepaintManager$ProcessingRunnable@2f61d502,notifier=null,catchExceptions=false,when=1698710866849] on sun.awt.windows.WToolkit@2ab4392b"
I searched the browser for this error.
"AWT events are not allowed inside write action" error message typically indicates that an AWT event, such as a UI update, is being triggered from within a write action in a Swing application.
And this error in ApplicationImpl.java:182
Could that be the problem? You can check it first.
