In most cases, there is no need to handle this exception manually. If this exception occurs, it usually means it is a bug in your code rather than application itself. Check your code first. The most of misuses comes from as follows.
button1 = poco('button1') time.sleep(10) # waiting for long enough before the UI hierarchy changing button1.click() # PocoTargetRemovedException will raise at this line. Because the 'button1' is not on the screen.
