When I launch the Telerik Report Designer i now get the the error below, also pictured in the attachment. I was able to launch and use the application once before, but now only get this error.
"An error has occurred while merging the resource dictionaries. Make sure that no assemblies with Telerik Controls for WPF reside in the same directory as the application executable.
Error of type 'Telerik.ReportDesigner.Core.AppResourceMergeException' was thrown."
This seems to be the same issue mentioned here in another question on this forum.
Below is the folder with the exe files for the application. I have tried restarting the computer, reinstalling the application, and repairing the application. None of these have fixed the issue.

Hello Alexander,
Based on the error message and your description, the issue is likely caused by missing or conflicting assemblies in the directory where the designer deploys its dependencies.
Please open the path '%temp%' in the Windows Explorer and then navigate to the subfolder 'Telerik ReportDesigner {version}', for example, 'Telerik ReportDesigner R1 2023 17.0.23.118.xxx'.
The path should look like 'C:\Users\arabadzhiev\AppData\Local\Temp\Telerik ReportDesigner 20.0.26.304.849'. Here are the Telerik DLLs that should be deployed there:
Telerik.ReportDesigner.Common.dll
Telerik.ReportDesigner.Configuration.dll
Telerik.ReportDesigner.Core.dll
Telerik.ReportDesigner.Interfaces.dll
Telerik.ReportDesigner.Packages.Core.dll
Telerik.ReportDesigner.Packages.Design.dll
Telerik.ReportDesigner.Packages.ExportTemplateWizard.dll
Telerik.ReportDesigner.Packages.ImportReportLibrary.dll
Telerik.ReportDesigner.Packages.ReportDesigner.dll
Telerik.ReportDesigner.Packages.ReportServer.dll
Telerik.ReportDesigner.Packages.Toolbar2.dll
Telerik.ReportDesigner.Shell.dll
Telerik.ReportDesigner.Theme.dll
Telerik.Reporting.Data.Schema.dll
Telerik.Reporting.Design.Components.dll
Telerik.Reporting.Design.EndUserDesigner.Components.dll
Telerik.Reporting.Design.EndUserDesigner.dll
Telerik.Reporting.dll
Telerik.Windows.Controls.Docking.dll
Telerik.Windows.Controls.GridView.dll
Telerik.Windows.Controls.Input.dll
Telerik.Windows.Controls.Navigation.dll
Telerik.Windows.Controls.RibbonView.dll
Telerik.Windows.Controls.dll
Telerik.Windows.Data.dllIf you have used the Telerik Report Server with the designer, the assembly 'Telerik.Reporting.Services.HttpClient.dll' should also be deployed there.
Note the Telerik.Windows.XXX DLLs in the list. These are the Telerik UI for WPF dependencies of the designer, which is a WPF application. I suspect some of them are missing in your designer's folder.
If some of the above DLLs are missing, you may safely delete the whole folder. Upon restarting the Standalone Report Designer, the folder will be recreated, and the designer will redeploy its dependencies. The 32-bit (x86) and 64-bit designer versions use the same folder for their dependencies.
If the problem persists, please send us the following logs:
