The problem is exactly the same as described here - https://stackoverflow.com/questions/52484814/oracle-sql-developer-problem-initializing-welcome-page

Indeed, the Open JDK was installed. I installed Oracle Java 8 JDK, chose a new version of java after that, checked the environment variables, but still the problem remained - sql developer runs with the same error - Problem initializing the JavaFX runtime. This features requires JavaFX. Tell me, who knows, please, what have I missed?

    1. Look in the file "CATALOG_GDE_INSTALLED_VASH_SQLDEVELOPER" /sqldeveloper/bin/sqldeveloper.conf for the value SetJavaHome.
    2. For Windows, you can use the version "with JDK included" Oracle SQL Developer Downloads
    3. As far as I understand, JavaFX is needed only for the Welcome Page, this is not necessary for the work of SQL Developer itself. Try to somehow get around this page.
