Thanks for sharing the backtrace. To help us investigate further—especially since there are no reproduction steps—could you please include additional details, such as any exception information or diagnostic messages, if available?

At first glance, this issue might be related to #2241. As mentioned in this comment, we're actively working on improving the performance of the message bus—which is notably referenced in your backtrace.

Looking forward to any extra info you can provide! 🙏

Hi @philip-lulu 👋

We have released v2.28.0 which includes a performance improvement related to Feature-communication in the SDK. There is a high change it would fix your issue, which is why I'm closing it. In case it wasn't the case, feel free to re-open it with more information and reproduction steps, as requested above.
