Unable to use Wayland

We should probably treat the Wayland and X11 issues separately so I'll just focus on the former...

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Run these commands:
    journalctl -b0 > journal.txt
    journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.

2. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

I have multiple crash files:

_opt_brave.com_brave_brave.1000.crash
_usr_bin_gjs-console.1000.crash
_usr_lib_xorg_Xorg.0.crash
_opt_Signal_signal-desktop.1000.crash
_usr_libexec_goa-daemon.1000.crash

2. I have run the ubuntu-bug command against each (xorg required sudo due to being owned by root), each popped up with a bug submission, so I sent it, but was not provided with any bug IDs. How do I retrieve these? I assume the contents inside the .uploaded files:

0e5027b2-6cfe-11ee-9aee-fa163ec44ecd
7bb73989-6d05-11ee-9aee-fa163ec44ecd

The problem is xdg-desktop-portal:

Oct 18 12:30:55 framework xdg-desktop-por[2907]: GError set over the top of a previous GError or uninitialized memory.
                                                 This indicates a bug in someone's code. You must ensure an error is NULL before it's set.
                                                 The overwriting error message was: Error calling StartServiceByName for org.freedesktop.impl.portal.desktop.gtk: Timeout was reached
Oct 18 12:30:55 framework xdg-desktop-por[2907]: Failed to create settings proxy: Error calling StartServiceByName for org.freedesktop.impl.portal.desktop.gnome: Timeout was reached
Oct 18 12:30:55 framework xdg-desktop-por[2907]: No skeleton to export
Oct 18 12:31:08 framework systemd[2479]: <email address hidden>: start operation timed out. Terminating.

which may be a result of "Purged ubuntu-desktop and gdm3 completely and reinstalled". So I'd suggest reinstalling Ubuntu from scratch.
