That happened to me yesterday on my work laptop. System 76's help documentation said to chroot in from rescue media, uninstall the drivers, then reinstall, and that worked fine, so it's now running 465 perfectly well. No idea why the straight upgrade path doesn't work. But that's completely an Ubuntu problem, not NVIDIA. Like a (currently) higher up comment says, NVIDIA on Linux works fine as long as you're running the latest version of everything. My main desktop was built last April and I've been running Arch with RTX 2070 and the latest NVIDIA drivers ever since first boot and it has never given me any trouble, video or audio. My display is a 50 inch OLED connected via HDMI and audio a 5-channel soundbar with external subwoofer using eARC from the display. Everything is fine using GNOME defaults. NVIDIA provides the nvidia-xconfig tool to autogenerate the X configuration, but you don't need it. It runs fine with no config. Wayland has worked for over a year, too. You can go look at the PKGBUILD file for Arch's PulseAudio installer and it isn't doing anything special, either, just applying the suggest default from PulseAudio's documentation making the ALSA default module pulse. The only reason NVIDIA on Linux gives people so many problems is they're trying to run old versions of everything on enterprise-oriented Linux distros or "long-term support" without purchasing support. If you want the latest hardware, use the latest software.
