Cannot invoke "org.eclipse.xtext.ui.editor.preferences.IPreferenceStoreAccess.getPreferenceStore()" because "this.preferenceStoreAccess" is null

Dear All, I've the same problem. I’ve also completely deinstalled eclipse 2023-09 and removed all folders for eclipse etc. Installed the previous version, we where the ANTLR plugin worked, but I got the same error.

antlr / antlr4

Cannot invoke "org.eclipse.xtext.ui.editor.preferences.IPreferenceStoreAccess.getPreferenceStore()" because "this.preferenceStoreAccess" is null #4458

When I was using eclipse version 2023-09, importing the plugin antlr4 ide 0.3.6 and using SyntaxDiagram, I encountered the following error. May I ask everyone how to resolve it? Thank you.
