WordPress not editable using Edge Browser

I recently migrated the site to a new host. However, when I use the MS Edge browser, the site is not editable. I can access the Admin Dashboard etc as normal, but when I click on a page or post, I get presented with a blank page. All works normally in Firefox, so it seems to be specific to the Edge browser. Not sure if this is a browser issue, a theme issue or even a host issue.

Edge version is 111.0.1661.44 (Official build) (64-bit)
