title: Python 3.10 warning
body: <pre><code>warning: PYDEVD_USE_CYTHON environment variable is set to 'NO'. Frame evaluator will be also disabled because it requires Cython extensions to be enabled in order to operate correctly.
  C:\Program Files\JetBrains\PyCharm Community Edition 2021.2.3\plugins\python-ce\helpers\pydev\pydevd.py:1844: DeprecationWarning: currentThread() is deprecated, use current_thread() instead
    dummy_thread = threading.currentThread()
  </code></pre>
  <p>I installed the newest version of python, deleted older one and this warning poped up. Python codes run as usual, but this message pops up after debugging. I use Pycharm as an IDE. How to resolve this issue?</p>
