Gnome doesn't launch and I get a login loop

Hello, community.

Since yesterday I have a very big problem: when I type my password in order to start my session in GNOME the screen gets black and again it asks me the password. The only one desktop that let me launch a session is IceWM and I need the GNOME one.
The last time that I could work in GNOME desktop I installed Anaconda in order to use Jupyter for programming in Python. I don’t know if that could make any damage to the GNOME desktop.
I can’t work in IceWM because I can’t set the wireless connection to internet (WIFI). At this moment I can post because I’m connected by the internet cable but themost of time I have to use WIFI connections. In GNOME is very easy to set the WIFI connection but in IceWM I don’t know how to do it.

What I want is to fix the GNOME desktop, I mean, I want to launch the GNOME desktop normally. How can I do it?

Thanks for your help.

You should still be able to use NetworkManager with IceWM…
