Hello Syncfusion team,

Recently some of our users reported this error many times when renaming file in filemanager. the error log message is:

It happened for me once. I selected a file and clicked rename from toolbar, after entering the new name and pressing Enter on keyboard, I got this error. when I refresh the file is renamed successfully. it didn't happen all times, but this error occured 29 times from 19/8/2024 until 3/10/2024
