images/graphs in downloaded PDF are missing BUT do show when viewing via browser
i have adobe reader v.2024.004.20220-64bit and use Chrome as browser .
I recently downloaded a pdf file from a research website but when i opened it i found certain images/grpahs were missing.

However if i view the same pdf file via chrome , these images ARE visible.

These images are also displayed if i use a different pdf reader like PDF24.
I uninstalled and reinstalled the Adobe reader but i still see the same problem. The app itself also generated an error message i.e.

but i think this is more an error with the app rather than the author.
Can anyone shed any light on this very situation?
