Upgraded to debian 13.0 from 12.11 and now unit NetworkManager.service could not be found. How do I install a network manager now?

I edited the new debian.sources file in /etc/apt/sources.list.d according to debian instructions, started to upgrade and successfuly upgraded to 13.0, at least core debian (can use mpv, vlc, thunar, libreoffice...)

Problem is, this notebook with debian 13.0 doesnt have a working network manager and there are still 900 packages that need upgrading.

The command I entered in the terminal: sudo systemctl status NetworkManager.service returns: unit NetworkManager.service could not be found.

I have an android phone I thought I could use as a network hotspot or maybe tether, but debian 13.0 doesnt recognize it, so I really dont know what to do

Lan cable didnt work either.

Help appreciated

ETA: THANK YOU GUYS FOR YOUR AWESOME HELP!!!

special thanks to InnerScientist and stuner for their approach but what worked was what IHave69XiBucks proposed.
