Why are my forms giving an error message?

I am attaching documents for my application and they are not opening once saved to the document. They are attaching initially but once I come back to reopen them from the application it wont allow, please help!

Please note that access to such files depends on the permission set by the form owner.

Unfortunately, I could not check the form or the account associated with your screenshot since its blurry.

Can you please share with us the complete URL of the file you are trying to access or the URL of the form you have just filled out.
