Error - Fatal: Launch Error: Could not launch JNLP file. The application has not been initialized.

Hi IcedTea-Web Support Team,

One of the users for Rapid Response application is encountering an issue when attempting to open a Kinaxis Rapid Response JNLP file using javaws.exe. It will return a Fatal Read Error: "Could not launch JNLP file. The application has not been initialized."

OpenJDK: Eclipse Adoptium jdk-8.0.332.9-hotspot
IcedTeaWeb version: 1.8.8
OS: Microsoft Windows 11

I have attached the error message and the error log for your reference.

Troubleshooting that had been done from our side is:
1. Clear Java cache by purging them in the itweb-setting
2. Clear the temp and %temp% cache files
3. Clear history from browser
4. Deleting old JNLP files
5. Login using other browsers
6. Initialize JNLP file with javaws.exe

7. Reinstall Eclipse Adoptium and IcedTeaWeb

But the issue is not fixed. User is still unable to launch the application.
Please help to advise what can be done to fix this issue.
