Hi Jamal,

This is a similar issue as described here. There is something wrong in the Modeler settings with respect to the location where Java is installed.

Could you try the following advice, copied from the other post:

Can you please try the below steps as work around and let us know if this works for you :

  1. Open preferences by File menu --> Edit --> Preferences
  2. Mention your JDK location in the 'JDK directory' field. (Like : C:\Program Files\Java\jdk1.8.0_144)
  3. Press 'OK'
  4. Ignore the crash and kill the modeler through windows task manager
  5. Open the modeler again
  6. Preferences should set and modeler should work fine.
