when i use Windows.Data.Pdf.PdfDocument to load a pdf file which sizes more than 2 GB, it crashed immediately.
No matter what you use LoadFromStreamAsync or LoadFromFileAsync, it just crashed with no information.
i can't catch this crash with try catch.

2021-01-29T01:04:29.81+00:00 Yes,it's a uwp app written by c# . I have also tried the official demo to open the same pdf file . It also crashed too.
But other pdf apps such as adobe reader or foxit reader can open the file normally.
I guess , it crashed because of the file sizes.
I have tried other files less than 2 GB, it works well.
The largest size of pdf files i tried is 1.98 GB, it can open normally.
But it can't work with more than 2 GB files. -

2021-02-10T03:31:14.177+00:00 @buskysnow I tried to open a pdf file of about 3.4 GB by using the official example. It took a few minutes and finally succeeded. It is better if you could try to open a large pdf file in another machine which has larger available space to check if the limitation of size of pdf file to be opened by PdfDocument API is relative with your local machine.

Crash is not catchable which makes it really hard to find reason for issue or workaround.
I've tried the file in the official demo app and it crashes too. The file can be opened in other PDF software (including Edge - although slowly - which is funny because I think it uses the Windows.Data.Pdf library as well if I'm correct?)
After a bit more research, it seems the size is indeed what makes it crash. Another PDF lib I tried crashed similarly when the stream length exceeded Int32.MaxValue. The exception was catchable in this one so I could get a proper error message.
My laptop has 16GB of ram (nothing else running really) and 140GB free SSD space so I hope that's not the issue.
Not sure how you managed to open a 3.4GB file. Care to exchange files so we can try and pinpoint where the issue might come from exactly? I can provide a storage link.

Thanks
