I also use the YouCompleteMe plugin without problem
with the latest vim.
However vim built with libpython3 (or libpython) unfortunately
gives many warnings. This is explained here:
https://github.com/python/cpython/blob/master/Misc/README.valgrind
I just avoided the warning in libpython3 by doing this
on xubuntu-18.04.4:
1) download and build Python3 source code:
$ wget https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tar.xz
$ tar xvf Python-3.8.2.tar.xz
$ ./configure --with-valgrind--enable-shared
$ make -j8
$ sudo make install
$ sudo lddconfig
(note the --with-valgrind option which is needed to avoid valgrind errors)
2) rebuild vim
$ cd vim
$ rm src/auto/config.cache
$ ./configure --with-features=huge --enable-gui=gtk3 --enable-python3interp=yes
$ make -j8
$ sudo make install
3) rebuild the YouCompleteVimPlugin
Assuming you installed it with Vundle, then you can rebuild it with:
$ cd ~/.vim/bundle/YouCompleteMe
$ ./install.py --clang-completer
And then I can run vim with valgrind without the ugly
valgrind errors. Well, I still get a couple of errors
with valgrind in libpython but far less that I used to see
and only at startup. I still get:

And a couple more but only when starting vim, after that
don't get more valgrind errors anymore.
Can you try something like that too?
