Unable to export to any format on ubuntu 22.04

I tried to export the simple arrow in any format, but it doesn't work.

My operating system: Ubuntu 22.04

My java version :

openjdk version "11.0.28" 2025-07-15

OpenJDK Runtime Environment (build 11.0.28+6-post-Ubuntu-1ubuntu122.04.1)

OpenJDK 64-Bit Server VM (build 11.0.28+6-post-Ubuntu-1ubuntu122.04.1, mixed mode, sharing)

Below is the log when I tried to export the diagram from the graphical interface via: File>Export

[INFO] Running on Linux [INFO] Working directory: /home/dung/app/Feyngame [INFO] Loaded 3 default styles [INFO] Detected external program 'ps2pdf'; enabling PDF export [INFO] Loading fallback default model [INFO] Found 17 line configurations [INFO] Found 74 vertex rules [INFO] Loaded 3 default styles [INFO] Starting diagram export to "/home/dung/app/Feyngame/Untitled.png" in format "png" Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.lang.Double (java.lang.Integer and java.lang.Double are in module java.base of loader 'bootstrap') at java.base/java.lang.Double.compareTo(Double.java:49) at java.desktop/javax.swing.SpinnerNumberModel.incrValue(SpinnerNumberModel.java:362) at java.desktop/javax.swing.SpinnerNumberModel.getPreviousValue(SpinnerNumberModel.java:401)
