[issue45294] Conditional import fails and produce UnboundLocalError, if a variable machting import name is used before

[arts stars]

New submission from arts stars <stars-of-stras at mediapromo.be>:

Hello,

I have this situation:
----------------
def test():
    
    if True :
        print("Exception"+DiaObjectFactoryHelper)
    else:
        from . import DiaObjectFactoryHelper
        pass
        
test()
---------------
it generates instead of (like the the line 'from . import' is commented) : 
"NameError: name 'DiaObjectFactoryHelper' is not defined"
this:
UnboundLocalError: local variable 'DiaObjectFactoryHelper' referenced before assignment


PS: The github authentificatiion did not work, did not manage to grab email even if set public
