This usually means an inconsistency between the different builds of
software you built at different times.

E.g. have you rebuilt vim against your newly built python?

The fix is to clean the bad builds and build them from scratch, once
you've identified where the bad builds are.

Let's narrow this down again:

I really appreciate your intent to help!

 

- do you see this with vim --clean +'py3 import socket'
- do you see this with python3.8 -c 'import socket'

This should let you decide if the problem is with your vim build, or
with your Python build.

I did some similar experiments based on suggestion I got at an online gitter room for YouCompleteMe from the maintainers itself. I did rebuild Vim, but the issue still occurred. So, after a bit of googling, I found someone suggesting just to have following done before building Vim (https://github.com/ycm-core/YouCompleteMe/issues/3580#issuecomment-589933447):
     $ export LDFLAGS="-rdynamic"

This made it work!

Then, I still saw some issue in starting YCM server, which was due to LD_LIBRARY_PATH not having path to locally installed Python3 libraries.

Now, it works fine. I am using 'clangd-completer' for semantic completion within Vim and the one packaged with YCM didn't work, so I used a different one (which luckily I already had available).

Thanks,
