Hi mm14222 ,

 

Refering to this case, The issue is seemed related to the feature enhanced-dataset-metadata. Please disable it in the lastest version and downgrade your Power bi desktop to check again.

Thanks for your kind support, yet even after almost 30 days and disabling the Enhanced Meta Date Format preview feature, it is still not working. 

 

I will downgrade again to the previous version, however, I will be losing a lot of the new fixes and features introduced in March and April version. 

Who I should escalate this issue to?  please help.
