It doesn't occur when changing the projects line endings to unix, i.e. \n only.

To reproduce

/edit add kdoc to this function on accepting the result (in my case produced by a local llama3 via LM Studio), the given error occurs. no change is applied.

Log output

nothing that looks relevant

@h34tnet thanks for sharing this—do you see the same thing for Ctrl+I (inline edits)? I'll test this on my windows machine before the next release
