I downloaded Mcreator 1.9.0. I really wanted to test out some of the new features, like the potion effect element. However, when I clicked 'new workspace' and named it, it came up with the following message:
Workspace Open Failed!
The workspace you are trying to open is not valid Mcreator workspace or is corrupted!
If you did not change the folder name and are seeing this, the workspace file might be corrupted.

(I pasted it in here because it's quite short. If you want it moved to pastebin I can do that).
