Save for Web Error - High quality GIF
Hello, I'm trying to export a GIF from Photoshop CC (2017) but I keep getting the following error message:

It is an image sequence originally rendered from After Effects CC (2017) - with images named from [...portrait_black_V2000.jpg - ...portrait_black_V2250.jpg].
I have kept the frame rate at 24.972 (what the original video file was set to) and each image is 2000x1600px.
I'm working on this machine:

I'm not sure what other info to provide, I've tried searching other forum posts but solutions seem to be very specific to the error/system.
Any help greatly appreciated!
Rosie
