Finished installation on Ubuntu; anaconda navigator won't open

I just installed Anaconda following the steps on the website. Everything seemed to work well except that at the launch of navigator, it hangs after throwing the following warnings and failures:
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
MESA-LOADER: failed to open crocus: /usr/lib/dri/crocus_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
failed to load driver: crocus
MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
Any ideas?
Thanks!
