Hi All,
We recently created new (on-prem) development virtual machines with the platform updates for version 10.0.21 for finance and operations apps (October 2021). I'm working on a custom data entity and everything is compiling fine. However, when I go to test it, I need to refresh the data entities list in the data management workspace framework parameters form. When I click on the framework parameters tile, nothing happens. I tried debugging and found an exception is being swallowed in the DMFParameters form on the DMFBYODParameters.insertDefaultValue method when it tries to get the CLRInterop type for Microsoft.Dynamics.AX.Framework.Tools.DMF.ServiceProxy.DMFSharedTypesServiceReference.ServiceContractClient:

I'm unable to debug into CLRInterop::getType. The exception is mentioning a null reference

I wondered if we are missing some component or configuration process or possibly a permissions issue? I checked the event viewer and didn't find anything useful in there. I'm attempting to do a full build of my custom models and checked the "build referenced packages" check box to see if that would help but I'm not confident about it. Does anyone have a suggestion on how to troubleshoot this problem?
