    Status: Open => Answered

RaiMan proposed the following answer:
a better version of your snippet:

def text_shrink(Reg): # continously decrease region until OCR gets a match
        texts=""
        Reg=Reg.grow(30,30,0,0)
        while texts == "" and Reg.getW()>61:
            Reg=Reg.grow(-30,-30,0,0)
            texts=ExtractAlphanumeric_all(Reg.text()).strip() #crash here on OCR
        return texts

--- I cannot see any information about a "crash" (besides that the
script does not come back)

--- your function ExtractAlphanumeric_all() might have problems (endless
loop?)

--- generally it does not make sense to shrink a region, that does not
have text, to eventually find text in the shrinked region.
