Started receiving an Import Error after upgrading to v5.35.0

[mister.mba]

Hello ~ I've been using Calibre for almost 10 years now. It's worked great for converting E-books for my iPad Mini and my wife's Kindles. Last week when we upgraded to v. 5.35.0 we both started receiving the error message below when trying to use the Connect/Share menu option to Send E-Books to Selected Recipients. FYI: we're using new LG Gram laptops running the latest version of Windows 11 (21H2). Any advice or workaround would be greatly appreciated! Thanks in advance...

Calibre Import Error after version 5.35.0 install

Thanks for checking into this minor issue. I had a feeling I was not the only one who was affected by it. I just upgraded my Windows 10 PC to v5.35.0 and am getting the same error. I will back out the upgrade while a workaround or update is developed. When I look in Windows Explorer for the path listed in the details, I noticed it appeared there was no "python-lib.bypy.frozen" folder; but when I try to create one, it tells me that it already exists (I am seeing the hidden files). Thanks again!

You will notice that a file called python-lib.bypy.frozen exists in the .bin directory. That file is a bundle of the python interpreter, code and dependencies in a single file.
