I wanted to share this in the IoX launcher, but it is locked.  I was getting this error after doing a windows update, java update.  I did the usual clearing of the temporary files/applets.  Still go the error.  Tried using windows control panel to delete Java and resinstalled from the Java website, same story.  Unchecked and checked keep temporary files box and still.  Finally, I fixed it by using the Java website's uninstaller and the offline installer.  https://www.java.com/download/help/troubleshoot_java.html

Perhaps this may save someone some time in the future.

@apostolakisl what version of Windows were you updating?

@Geddy Win10pro   Interestingly, for the last few months, I wasn't able to use IoX either.  I have to use the java console you access from ISY itself.  And then after this update, java just wouldn't open at all.  And just now, windows is showing another update.  UHGGGG!

Thanks for the post.  I also had this issue yesterday with Windows 11 Pro.  I finally uninstalled from windows add/remove programs, rebooted and installed with their off line installer.  Very annoying.  I submitted a support ticket with all the Java console errors, hopefully @Chris can make sense of it all.
