To open this page in Internet Explorer mode, reinstall Microsoft Edge with administrator privileges.

It appears to be related to the Internet Explorer patch version. If you go to edge://compat/iediagnostic check to see if Internet Explorer mode API version shows "Not Supported".
If so, you'll need to update your Internet Explorer version. I found that working machines had KB4519974 installed, whereas the broken ones were on an older version of IE. Once I installed KB4519974 and rebooted, it resolved the issue.
