Hi @louis77, can you please share what you were doing when this error occurred? Thanks!

[louis77]

Hi @50Wliu , I had a 15 mb XML file in my clipboard and pasted that into the editor. The XML itself was valid, but probably everything in one line.

No further reports and the editor has known issues with very long lines so closing this issue here.
