It seems references to telerik is breaking Microsoft Report Designer. Every time I try to add a dataset to a report, visual studio crushes and closes without giving an error message. Adding a report via Report Wizard does not also work and throws the error "Could not load file or assembly 'Microsoft.AnalysisServices.AdomdClient" even though I have installed the said library. If I remove all reference to telerik everything works. I'm using Telerik UI for ASP.NET AJAX R2 2020, visual studio 2019 with target framework of 4.8. I have tested earlier version like Telerik UI for ASP.NET AJAX R2 2019 but I'm getting the same error. I have been trying to resolve this error for the last 5 days without success. Any help will be appreciated. Thanks.
