Age of Empires Definitive Ed keeps crashing

The attached error is displayed “Warning: a running process may be interfering with the correct operation of Age of Empires” and the game returns to the home page but with no options other than exit available. I am running Windows 10 and have no anti-virus other than Windows Defender running. I have installed no new software. I have reinstalled the game from scratch and the problem is still occurring.

Any help appreciated. Thanks.
