Extensive problems with Hyper-V Quick Create 22.04 image. Can I report bugs? Should I use something else?

Question

The 22.04 image installed via Hyper-V Quick Create seems to be riddled with problems.

1. Should I be using another approach to run Ubuntu in Windows? WSL2 is not suitable for my needs (and is similarly rough anyway).
2. Is it possible to report bugs anywhere? The usual channels are very much about particular packages, but this is on a distribution level. The issues include:
   • Apt and snaps fill the disk after a couple of days of automatic updates.
   • Constant popups about systemd SIGABRTs and xrdp crashes.
   • Snap auto-updates pop up in gnome but cannot install because gnome is using them.
   • xrdp file shares cache out of date info.
   • xrdp file shares are inauthentic, don't work with docker volume mounts.
   • xrdp sessions don't cache sudo passwords.
   • gnome-control-center cannot apply some settings, such as ethernet ipv4 settings, in an xrdp session because it doesn't consistently sudo.
   • Hostnames only work intermittently.
