I am experiencing an issue when trying to "configure" (wrench button) my Minecraft Java Realm. I am able to load the realm, and other users can also access the realm. But the Realm is now stuck on the last world that I loaded and I am unable to "configure" to change this. 

I have worked through each of the troubleshooting steps with support to include: 

• logging off and on again. 
• updating windows
• updating video card
• re-installing the launcher
• running the launcher executable directly (alternate launcher)
• disabling AV and Firewall
• rebooting and retrying after each of these steps produced the same results. 

Additionally I have loaded the minecraft java launcher on a clean/new PC, with nothing else installed and signed in to my account. When launching minecraft java and attempting to "configure" the realm, I receive the same result. Crash. The crash error message pops up in the Minecraft Launcher. 

ERROR: Game Crashed

The game crashed whilst rendering screen
Error: java.lang.NullPointerException: Cannot invoke "java.awt.image.BufferedImage.getWidth()" because "☃" is null
Exit Code: -1

I have also attached the crash report.
