This is a known Onebox VM upgrade issue due to the update scripts not being able to update the components in the
c:\AOSService\webroot\bin folder.
See this community forum article for the issue/details:
Summary of the fix from that article:
Thank you! I was able to solve this problem by copying all 8 Microsoft.Dynamics.AX.Framework.Tools.DMF.* files from AOSService\Webroot\bin folder of a cloud-hosted 10.0.21 vm to the same folder (AOSService\Webroot\bin and NOT AOSService\Webroot) of my one-box 10.0.21 dev vm
To fix in the Onebox VM copy the files shown below from the
Upgrade source (under DIXFService\Scripts\VER2019) to c:\AOSService\webroot\bin:
Ensure you stop the WWW service and the DMF and batch services before you attempt to copy. Only copy the hihglighted files from the VER2019 folder to the c:\aosservice\webroot\bin folder.
restart the WWW service and the batch and DMF and the DMF Framework parameters form will now open.
