After Effects - default dual viewport and no way to switch back to one viewport

[Didadida]

This became my default screen. I just don't see the way to switch it back to a single viewport. Can someone help, please?!

Hi fh74872557,

Thanks for reaching out.

Add a 3D layer temporarily to bring back the Select View Layout option.

Let us know if it helps.

Thanks,

Nishu
