Hi Inuzuka,We suspect that there is a mismatch between the registered
license key version(v16.4.0.*) and the version of Syncfusion packages(v17.1.0.41)
used in your application.Find
below the knowledge base article to know about which version license key should
use in application,

https://www.syncfusion.com/kb/8951/which-version-syncfusion-license-key-should-i-use-in-my-application If you
are using Syncfusion assemblies
uget packages from
installer or from nuget.org ,
you should generate and register the corresponding
version and platforms license
key in your application to avoid trial license
warning.  Syncfusion license keys are version and
platform-specific and the generated license key is just a string that needs to be
registered before any Syncfusion control is initiated.Please, ensure that all
the referenced Syncfusion assemblies\NuGet packages are all on the same
version(17.1.0.41) as license key’s version(17.1.0.41) in your project. If still not resolved,  please share us the
following details to investigate issue from our side,
