How to Fix Microsoft Edge Freezes or Crashes When Opening PDF Files on Windows

Microsoft Edge, a built-in browser is also the default application to open and view PDF files in Windows 11/10. Nowadays, it is a common practice for people to communicate and send PDF files as attachments to emails. To open and view these PDF files you need to double-click on the file and Edge opens with the selected PDF file.
