Legacy title crash in export horisontal scroll

[defaultakicuvf6ppt7]

I have a long text that should scroll from left to right (takes 50min for the entire text) where legacy title is the easiest way, as they allow me to add a long text and just adjust the duration. However, when exporting, an error message comes up and I have narroved it down to the legacy title. My other options would be to add text, and key frame the motion, but it is not possible with such a long text running horizontally. The roll buttom works great for vertical credits. Any advice on how to make this work? I rather not have to keyframe sentence by sentence, as this will add another day of work.
