Connection interruption on initialisation since v20.0: Cannot find or open the PDB file

Dear Support,

After changing to v.20.1.0.52 (from 19.4.0.54), I get a connection error when initialising SFChart components. 

The error is shown in console is: 

[System.Nullable`1[System.Double][,]]

Loaded '/Users/Shared/Dev/PromotX/bin/Debug/net6.0/Syncfusion.Blazor.Charts.dll'. Cannot find or open the PDB file.

Loaded '/Users/Shared/Dev/PromotX/bin/Debug/net6.0/Syncfusion.Blazor.DataVizCommon.dll'. Cannot find or open the PDB file.

Loaded '/Users/Shared/Dev/PromotX/bin/Debug/net6.0/Syncfusion.Blazor.HeatMap.dll'. Cannot find or open the PDB file.

Exception thrown: 'System.IO.InvalidDataException' in Microsoft.AspNetCore.SignalR.Core.dll

Exception thrown: 'System.IO.InvalidDataException' in System.Private.CoreLib.dll


After reload, it works, but after every new start of the app (build/run) the issue happens again when loading the charts page.

Reverting back to 19.4.0.54 resolves the issue.

Tested on macOS M1 and Azure AppService with both Safari and MS Edge browsers.


Please let me know if you need further input.

Thanks

Klaus.
