Timeline animation - error in the last frame
Hello,
I'm trying to convert a video I made in AE to a GIF animation in Photoshop, but it simply refuses to play or render the last frame of the animation. I've tried many times to make Photoshop open this frame, at least, but I can't even click on it. Since I need a GIF which will be repeated once, I get a visible incomplete animation. I've tried also to reduce the framerate in Ae, but it was useless.
Here is a print of my problem:

Can someone help me with this?
