How to click on TreeItem checkbox while Desktop is locked or RDP session is closed

Question

Hello I have following information about my UI and TreeView item in on of the windows:

>>> x.dump_tree()
Control Identifiers:

It seems that all possible control methods are allowed only if Desktop is active ( computer is not locked or RDP session is active)

Is there any way to workarround this with methods that can be used while the desktop is locked ?

Extra info: Tthe process is started as admin(python process too) and I've connected to the process using connect method. Backend of the app is uia

Python version: 3.7 , pywinauto 0.6.5

I'm attching UI screenshot for more clarification: enter image description here

Here is my code that I use but it works only if desktop is active:

def click_tree_button(app, window, button, timeout=DEFAULT_TIMEOUT_MINI):
    "Add descr. here"
    starttime = time()
    while time() - starttime < timeout:
        try:
            app.top_window()
            app.window(title_re=window).child_window(control_type="Tree").get_item('\\' + button).select().type_keys('{SPACE}')
            return
        except (pywinauto.findwindows.ElementNotFoundError,
                pywinauto.findbestmatch.MatchError):
            sleep(0.5)
    raise Exception("Cannot click '{}' tree button on '{}' screen".format(button, window))
