Fatal: Launch Error: Could not launch JNLP file.

I'm encountering an issue when attempting to open a JNLP file using javaws.bat. Occasionally, it returns a Fatal Launch Error: "Could not launch JNLP file." This error seems to occur inconsistently. When it does happen, simply restarting my PC resolves the issue. I'm unable to determine the root cause of this problem. I've already collaborated with my network team, and they confirmed that there are no blocks preventing the launch of .jnlp file applications. Any guidance on resolving this issue would be greatly appreciated.

OpenJDK : Azul Zulu 8.76.17(8u402),64-bit
IcedTea web: 1.8.8

Start with the attached alex_Log.txt and the javaws.bat launch path, comparing a failed JNLP launch with one that succeeds after restarting the PC. Review the reported OpenJDK and IcedTea-Web versions and determine a reproducible cause for the intermittent fatal error. Done means the cause and a verified resolution or clear diagnostic are documented.
