Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Bugs & Technical Problems Divinity Engine 2 issue "output spam detected"

Using the GOG version of the game and updated to the latest version.

I've used Divinity Engine 2 a couple of months back but now to create a project and it was working fine. Now when I try to load a current or try to create a new project I'm stuck at the loading screen and the same error messages keep cycling below.

Engine: Output Spam Detected Please Check This!
Code: Destination buffer too small to read line! Buffer size 1024, needed 1047.

This creates a large error log - got over 10GB before I had to end application with task manager.

I made sure to copy editor into the data folder and the install path hasn't changed since I last used the editor / engine. Checked the game data path in settings and its still correct.

I don't understand what these error messages are. Please help.
