Custom world gen settings causes minecraft to crash upon import

Upon import the file known as, a_worldgen_settings.txt, minecraft will crash when the settings are imported and doesn't give a chance of world generation. It gives this error in that box, "java.lang.NullPointerException: mouseClicked event handler", and the file used for generation and the crash report for the file are included below.

A seemingly related bug was reported in version 20w21a, but for superflat worlds.

After a bit more testing it seems that the reasons for the crashes I've experienced were related to an improper block state key being put in properties of water in which caused the crash. I used theses values (below)

"default_fluid": {
  "Name": "minecraft:water",
  "Properties": {
    "state": 0
  }

which lead to the crash after importing the file in the file manager, while if ("state": 0) is changed to ("level": "0") minecraft will subsequent run the code just fine.

also the attached file, a_worldgen_settings1.txt, is the working and updated file.

Can confirm @Austin, the level tag I was looking for (and was showing as in error in pre-6), is what you posted here.
