Installing bertopic cause Spyder 5.5.1 in Anaconda to not launch ith errors.

[rdsch2]

After upgrading Anaconda to 2.6.1 Spyder 5.5.1 which is installed does not launch after installing latest Bertopic (from conda-forge). These are the errors. Sypder launched before installing bertopic.

Traceback (most recent call last):
File "/opt/anaconda3/bin/spyder", line 7, in
from spyder.app.start import main
File "/opt/anaconda3/lib/python3.12/site-packages/spyder/app/start.py", line 25, in

This does not seem to be related to BERTopic but instead your spyder environment. Instead, I would advise starting from a completely clean and fresh environment before continuing.
