When I click on one of the grid headings an exception is fired and the grids has the spinning blue circle displayed. The grid becomes unresponsive.

Hi Chris, 
Thanks for contacting Syncfusion support. 
We have checked your reported issue in our side and this is not a Grid component issue. [Blazor] IL Linker not working properly, it may be the cause of an issue.  

We suggest you to disable the IL Linker which is present in your .csproj file. Please refer the following code snippet. 

    .  .  .  . 

Please refer the following link for more information: https://github.com/mono/mono/issues/12917   

For your convenience we have modified your sample where we have disabled the IL Linker. Please refer the below sample link. 

Please get back to us for further assistance.

Thanks Gurupriyadharshini for looking into this for me. No way I would have been able to work it out.

The VS Blazor template used when you create new s Blazor client app must include IL Linker. I have no idea what IL Linker is so will have to do some google searching to see what it's about.
