Error: Cannot place this file. Invalid PNG file in InDesign 19.4 on MacOS Sonoma 14.5
I have many Indesign files that seem to no longer work. I've recently changed to a new laptop, and resynced Dropbox with my desktop. I'm running Indesign 19.4 within Sonoma 14.5 on a MacBook air (the latest). In the thumbnail I can see all linked content, images (PNG), types and various fonts, etc.
The error message is: Cannot place this file. Invalid PNG file.
I can see this is an old issue here on the community, but nothing new about this error.
Any help would be most helpful.
