The last couple of hours I've been updating my python and anaconda packages, but I have hit a wall regarding this tqdm package. The first thing I tried was installing nbformat with:
conda install nb format
and got back:

I tried updating conda, but I get the same thing:
ERROR conda.core.link:_execute_actions(337): An error occurred while installing package 'defaults::tqdm-4.46.0-py_0'.
CondaError: Cannot link a source that does not exist. C:\Users\sergi\Anaconda3\Scripts\conda.exe

Finally I tried installing this tqdm package with conda install -c conda-forge tqdm, got the same error again.
I have also tried with conda config --add pinned_packages defaults::conda, but nothing seems to work.
If anyone has any idea of what's going on I would greatly appreciate some help.
Thanks!
