Yesterday the recently updated Edge caused the same crash.
If a program crashes, there will usually be a crash report in the event log. If Windows crashes, there may be a crash report, depending on circumstances. Event Viewer is thus the first place to look for details of what is happening. Press Windows key + R to open a Run box, type eventvwr and press Enter to open the event viewer. You'll find program crash reports marked as Error in the Windows Logs > Application log and OS crashes in the Windows Logs > System log.
Edge has its own crashpad recording details of what's going on if the program crashes.
Your best way forward is to submit feedback to the Edge team explaining exactly what happens. Use precise terms, not your interpretation of text you see (I don't think there's any error message in Edge that reads Page Unresponsive, for example). To submit feedback, in Edge press Alt-Shift-i or click ⋯ (Settings and more) > Help and feedback > Send feedback. Include diagnostic data and a screenshot if appropriate, and it should help to attach the latest file or two from the folder
%localappdata%\Microsoft\Edge\User Data\Crashpad\reports
If you include an email address, you'll receive an acknowledgement and probably a request for further data.
