FreeSpire.PDF produce error with multiple threading in c#

[airbusluc]

hi iceblue,

I appreciate your free version.
Currently, FreeSpire.Pdf converts pdf to svg very well when running single-threading.
But it crashes when running multiple-threading.
Please see attached image for details.
I have attached source code for 2 versions Single and Multiple threading.
I also have attached pdf files as testing data.
Hope the bug will be fixed soon.

Thank you and Best regards.
