"Premature end of file" (MCreator 2025.2)

Subject: Procedure Blocks Not Visible - I'm Getting a "Premature end of file" Error (MCreator 2025.2)

I am facing a serious issue in MCreator version 2025.2 and would appreciate your help if you could.

Summary of my issue: I created a new mod project. But my main workspace is completely blank and when I try to add mod elements, the procedure blocks (visual code blocks) are completely missing; that is, the block palette I would drag and drop is not visible at all. Also, I constantly get the following error message in the "Warnings and errors" panel: "Exception while compiling blocks: Premature end of file."

Explaining the Situation:

I am using the most current version of MCreator, 2025.2.

The problem occurred in a project that I had just created. I haven't added any mod elements or procedures yet.

There are no Turkish characters or special characters in the file path where my project is saved.

As you can see in the screenshot, the workspace is empty and there is nothing where the procedure blocks should be.
