I have a similar problem with the .ipynb notebooks and Spyder:

I can create a new notebook, but when I open one (from drive or from my hard disk) it opens like this:

... "cell_type": "code", "execution_count": 5, "id": "a0223996-7fc1-4d91-a975-00ebba92c6f9", "metadata": {}, "outputs": [ { "name": "stdout", "output_type": "stream", "text": [ "<class 'list'>\n", "<class 'numpy.ndarray'>\n" ...

I am not familiar with creating/managing conda environments. I tried it in "base". Then I read that it could be because of a conflict with jupyter lab (or something similar) so I tried to create a new environment (without touching anything), installed Spyder and the problem was there again.

Thanks in advance!
