I can't open my old workspaces.

Status
Fixed
Issue description

I downloaded and installed the latest version of MCreator but now, I can't open the workspaces I created with the previous version. I can only create a new workspace. What should I do? I can't remake my mods from scratch! After clicking on the workspace nothing happens. I managed to open one of the old workspaces by a miracle, but it took ages and the strangest thing is that it never happened before.

Issue comments

Attach an example of such workspace.

If workspaces are in MCR, you will need a legacy MCR converter, though.

Open .mcreator file of workspace and find line 

    "ACHIEVEMENT": 0,

and remove it. I will release a proper fix for this in the next udpate.
