Incapable d’extraire certain document et d’enregistrer des modifications

Hello,

I am trying to extract the pdf document which is located on the Sharepoint folder using the program Adobe acrobat standard, please see below a screenshot, and it gives me an error message that Adobe Acrobat cannot extract the document due to network error. Do you want to download and open the local copy of the document?
I was trying also to download the same pdf document directly from the Microsoft Sharepoint site into the computer and after that I was able to open the same document using Adobe Acrobat Standard
and modify it (insert another pdf document to merge them together) and save the changes on my computer and put it back on the Sharepoint site successfully. This was done to test whether the file is not corrupted or defective.
The probleme is that for some pdf files when I try to open them using the Adobe Acrobat standard, it gives me this error message and it does not work like it was working before while other files pdf on the same Sharepoint folder I can extract and modify via Adove acrobat standard without any issues.
So I also upgraded the computer with the latest windows system updades and drivers but it did not help to solve this issue, so it seems like it is not the issue with the network but in Adobe Acrobat.
Do you have any solutions for this issue?

Thank you.
