Hi Anderson,
Greetings from Syncfusion Support!
We have reviewed your query regarding the issue of Bootstrap version 5.3 not loading correctly in Blazor Theme Studio.
We have investigated the reported behavior and identified that a required theme variable was missing in the live environment, which caused the issue. This has now been fixed, and Bootstrap 5.3 is loading correctly in the Blazor Theme Studio. Kindly clear your browser cache and try accessing it again.
As an alternative, you can also download and use custom themes directly via our Blazor Themes npm package. Please refer to the documentation link below for detailed instructions:

If you continue to face any issues or need further assistance, please feel free to let us know. We will be happy to help.
Regards,
