When I try to run Calibre-portable.exe y have this message:

There was an error initializing the bypy frozen importer:
<class 'MemoryError'>: 
Traceback (most recent call last):
  File bypy-importer.py, line 250, in <module>
  File bypy-importer.py, line 195, in __init__

It only happens since Calibre changed to version 5 and on.
This very morning I've tried with Calibre 5.3

Thank you
