Script Fails When Translating from Khmer to English (Not using different provider)

When attempting to translate some example text from Khmer to english, the translator fails. It's able to translate English into Khmer I fail to see why it wouldn't be able to do both. Here's the test code that failed

translator= Translator(from_lang="Khmer", to_lang="English")
a_translated = translator.translate("ខ្ញខ្ញុំស្រឡាញ់មាន់")
print(a_translated)

and here's the ensuing error

Traceback (most recent call last):
  File "C:\Users\user\AppData\Local\Programs\Python\Python311\Lib\site-packages\translate\translate.py", line 45, in <genexpr>
    return ' '.join(self.provider.get_translation(text_wraped) for text_wraped in text_list)

StopIteration

The above exception was the direct cause of the following exception:

RuntimeError: generator raised StopIteration

Reproduce the Khmer-to-English example, then inspect translate/translate.py and providers/mymemory_translated.py, especially the failing match lookup shown in the traceback. Check the provider response for this language pair and run the existing test suite if available. Done means the example returns a translation without RuntimeError while preserving other provider behavior.
