app=Application(backend='uia').start(r"C:\Program Files (x86)\blue8\client\B8Analyser.exe")
time.sleep(5)
app=Application(backend='uia').connect(title='Main Window',timeout=10)

w1 = app.window(best_match='Main Window').wrapper_object()
w2 = app.window(handle=w1)
ctrl = w2['TreeView']

c1 = ctrl.get_item([u'xd Explorer', u'Annotation_AugCrime']).click_input(button="left", double=True)
c2 = c1.sub_elements()

@bharatrajs sorry for long waiting but I see that the error message is NOT from my branch. Can you please try with my branch again?

pip uninstall -y pywinauto
pip install https://github.com/vasily-v-ryabov/pywinauto/archive/refs/heads/uia_elem_init_crash.zip

After installing my branch, please run your test and provide full traceback.
