Hi Ashish,
Greeting from Syncfusion support.
We suspect that you are using the Syncfusion packages version below v20.1.47. We have introduced the license registration in the volume 1 2022 release i.e.(v20.1.47). So if you are using the packages below v20.1.47 then this issue will arise. Please upgrade your packages to the latest version to avoid these issue.
Please get back to us if you have any queries.
Regards,
Shyam G
