BUG: report connected to deleted semantic model cannot be opened in PBI desktop

Tip of the iceberg. I think there is a fundamental issue in the way PowerBi handles it's dialogs. I frequently experience an issue where the authentication window appears behind all other windows, with no way to bring it to the front. The app is rendered useless and the only way is to ctrl+alt+del. Happens in powerquery too, especially with a larger dataset and slower connection - some dialogs will take forever to open and when they do load, they load behind other windows. As for the payment of QA.. I 100% agree. I lose hours and hours of my day, which I cannot charge to clients, to work with MS support teams, replicating issues, only to be told it's by design, a known limitation, or not implemented feature. The majority of my work involves developing dashboards for clients using PowerBi, and I am ready to walk away from the product - just not worth it anymore.
