Parse pdf file?

Question

PHP

There is a need to parse a pdf file into more than 1000 pages. For parsing I use pdfparser https://www.pdfparser.org/documentation
When I try to parse this file I get an error

file_get_contents(): Filename cannot be empty

At the same moment, if you try to parse another pdf file with text in tables, it parses perfectly. I sin that the file itself has some kind of protection against such actions, I cannot re-get this pdf. I looked at the permissions of this file, everything is ok there, there are permissions to read and write.
Maybe someone has come across a similar one, if this is really some kind of protection, then how can it be disabled to read this file without any problems. Thanks
Maybe this will help the file was generated by Win2PDF
