Spent couple hours to try how to solve this problem, Using embeded QtWebEngine, instead of external browser, but when try to send_keys("some word") return "segmentation fault"
but its OK when send_keys without any string(send_keys("")), but its useless action
all webdriver action already under QThread

if you try code above, save as Chrome(without ".py") and make it executable
