amp_endpoint error

I am getting the following error on my site that occurs when using the new MS Edge Browser:

Notice: is_amp_endpoint was called incorrectly. is_amp_endpoint() was called before the parse_query hook was called. Please see Debugging in WordPress for more information. (This message was added in version 0.4.2.) in /var/www/vhosts/example.us/public_html/example/wp-includes/functions.php on line 5167

The reported error also breaks my layout. It goes away when I deactivate AMP. No other plugin fixes the error. The problem doesn’t seem to occur on Firefox or Chrome (at least it doesn’t show as an error). No way to know if it shows up on Macs.

Thoughts? I have no idea where to start on this. TIA
