This test was added in #181071.

Start with lldb/test/API/functionalities/scripted_frame_provider/thread_filter/TestFrameProviderThreadFilter.py, especially test_bt_provider_star_with_thread_filter, and reproduce it on Linux Arm. Read lldb/source/Target/StackFrameList.cpp around GetFrameAtIndex and the reported assertion, then compare the failing thread-selection path with the test's expectations. Done means the test completes without the assertion or abort.
