To access this fix, we suggest you update the package to 29.1.41 and we include the sample in the latest version for your reference.
Sample : Attached as a zip file.

Release notes: https://blazor.syncfusion.com/documentation/release-notes/29.1.41?type=all#file-manager
Root cause : Invoking the JavaScript method to set focus before the grid's selection change can cause a race condition in certain scenarios, especially when the component is disposed or when a container dialog that holds the component is closed during the process.
Regards,
Prasanth Madhaiyan.
