Ditto. Same problem.
Can't open PDF files in Egde on Windows 10 mobile
W10M 10.0.15254.248
Edge 40.15254.248.0
PDF starts opening in Edge, stops loading. Blank PDF page is displayed for a second. Then a blank HTML page, and the file reloads. Blank PDF page is displayed for a second and then an error page is diplayed "This page is having a problem loading" with URL:
ms-appx-web://assets/errorpages/ErrorPages.html?error=100000#file:///C:/Data/Users/Public/______.pdf
Started about around 13 February. Don't remember if any updates were installed before it stopped working.

Update: This is known behaviour as a result of February 14, 2018—KB4077675 Update to OS Build 15254.248
Source:
Microsoft
Update 2: The workaround proposed by MS is to download MS Reader to view PDFs, but with 15254.248 installed, the store does not allow MS reader to be downloaded with a message: "Powered by great new features in the latest Windows update. Get yours today." and a buttom Get updated which opens
https://forums.windowscentral.com/e...Fsoftware-download%2Fwindows10&token=KSr_b-l8 for desktop Windows 10 update.
If you've dowloaded MS Reader prior to KB4077675 installation you'll be fine.
If you haven't dowloaded MS Reader prior to KB4077675 installation you'll have to install a 3rd party app to view PDFs.
