After Effects Won't Import .swf/Animate File Correctly

[akat10]

I have 2 Animate files that I'm importing into AE. Both files are saved in seperate folders, everything is named correctly and all assets are placed in their correct folders. File A from Animate imports into AE correctly; it makes .swf files, everything animates as it should, it works fine. After Effects refuses to import File B right. Every asset gives a 'File cannot be opened, it may be in an unsupported format (86: 1 )' even though it's in the same format as File A. Dragging the files in directly gives me the same 'File can't be opened' message. It's not an issue of neither works, it's more one does, the other doesn't despite them being nearly identical. 

I've renamed the file, moved the folder, resaved the Animate file, restarted my computer, restarted After Effects, I can't figure it out. Other files open, but this one won't.

I'm using After Effects 2023 and Animate 2023 on a Macbook Pro, Big Sur 11.7.10.

Thanks for writing in. A couple of questions I would like to ask are:

1. The SWF files that are failing to import, do they have audio?

2. Have you used any scripts/expressions in Animate in this file?

Can you share the file with us for testing? Feel free to send it via DM if you don't want to share it publicly.

Looking forward to your response.

Thanks,
Nishu

They do not have audio, there's no scripts or expressions used. I realized it's more of a Animate issue than AE as it wouldn't even export properly in Animate. I figured out that I have to dump all my files on my desktop to be able to export it as a working swf, but I'm not sure why that works and frankly, it's an inconvenient solution. I'll still share the files!
