(so we can know if this is a potential cause of your issue)

• yes (which ones)
• no

Level of RxSwift knowledge:
(this is so we can understand your level of knowledge
and formulate the response in an appropriate manner)

• just starting
• I have a small code base

Just to make sure I understand... You forked the latest main branch, then built and ran the example app and it failed? I'm not seeing that behavior. Please provide the path you are using so I can reproduce the problem.

yes，I clone the latest main branch to local，open the Rx.xcworkspace with Xcode 15.4，then switch to RxExample-iOS scheme and Run，it's terminated as soon as it is started。

file path: Documents/Projects/RxSwift/Rx.xcworkspace
I use Xcodes to manage multiple versions of Xcode，and now version 15.4 is activated。
