Recently the pdf viewer has broken for me in obsidian, whenever I try to open a pdf file I am met with an empty page. This happens in a brand new vault with restricted mode enabled and after a fresh obsidian install. I see some errors in the developer console related to pdf.js.
Steps to reproduce
- Create a new obsidian vault.
- Add a pdf file to the vault.
- Click to open the pdf file in obsidian.

Expected result
The pdf file opens in the obsidian viewer.
Actual result
The pdf viewer opens but displays zero pages in the file and is blank. This happens with all pdfs.
