Issue Description: Users may be intermittently unable to open semantic models in Power BI.

More info: The errors and failures may vary each time this feature is used as the impact is intermittent. The errors manifest as the feature getting stuck while attempting to open or the feature failing to open at all.

A refresh and retry may help to circumvent the impact.
