Edit in Photoshop (Mac) - "Unable to Open in PS" Message after downloading

[haleeisforeal]

So I'm trying to "edit in photoshop" button. When I do this it will immediately say "Downloading Original" and eventually will say it's unable to open in photoshop. 

I don't want to delete these images BECAUSE

1. There's so so many I need to complete

2. All their settings were already applied to them 

3. It would take forever to upload and get the exact same edit on all of them 

WHY IS IT DOING THIS 

[haleeisforeal]

Can't pull the images into photoshop*

My LR isn't opening my images in PS either - I'm on a Macbook Pro 12.6, using LR 6 and PS 24.0. I finally saved out my image, made my edits in PS and re-imported.

Having the exact same issue. i could do this until 2 days ago but now, when I click "edit in photoshop" it says downloading original but the status bar doesn't move and then after a few mins, it gives me an error message. I don't get it..
