Prevent warning: Code path does I/O on the main thread underneath that can lead to UI responsiveness issues

Question

Hi,

I have noticed that there has recently been a warning for main thread UI hangs from Datadog (ver 2.15.0) on Xcode 15.4 (15F31d). I've attached a couple of screenshots. Do you have any insights into what could be happening to cause this and what I could do in my initialization logic that could prevent this from happening?

Simply enabling the RUM enablement in a background queue like DispatchQueue.global().async did not affect the problem at all. And the warning will stop appearing if I comment out the RUM enablement.

Please let me know if I am misunderstanding something in the initialization process or if there is an update that I will need to install later to fix the issue.
