Generate Image Assets maximum size limit

[RCaseyHfx]

Hello, I am trying to get Photoshop "Generate Image Assets" to export an image larger than 10,000 pixels.
I am trying to export an image 19384 x 4096, which is the original size of the canvas. At the moment it exports the canvas the correct size, but exports the image at 10,000 pixels and moves it to the top left corner.
This is my document setup

and this is what it exports .
the smaller images are all correct.
If I export an image 10,000 wide is it correct

As soon as I go above 10,000 it doesn't work.

Is there a way around this? I have not been able to find anything.
Any help appreciated.

Generator uses the Export module. Export is for intended for web/screen/mobile devices. The purpose of Export is to produce as small files as possible, and 14 000 pixels is outside the scope of Export.

For big images, Save As/Save A Copy in the normal way.

thanks for the suggestion. These documents are many layered, and exporting 40 individual layers from each, that rely on individual names for the layers being exported. Was working great until I needed to go with bigger images. The turning on and off layers, and  "save as" leaves too much room for human error, and takes a lot of time. With the layer names all the same in the template, then I may be able to use actions or script something to get what I need.
