Problem with launching Pixelmon, when starting: The game crashed whilst rendering overlay Error: java.lang.NullPointerException:

[nitsudll]

When I try to launch Pixelmon over the CurseForge app and press "Play Demo" after a few seconds the error plops up: "The game crashed whilst rendering overlay Error: java.lang.NullPointerException: Rendering overlay"

The crash report is here: https://pastebin.com/jXPjCuVS

Don't know how to fix this error sadly.
