I have the same issue since today. Running with GDB gives:

/edit:
Searching, Updating and Installing software works through flatpak on the commandline.
Apparently something went wrong with the automagic updates, flatpak update results in 42 missing updates, see flatpak-update_2020-01-12.txt (8.9 KB) but after applying them AppCenter is still segfaulting …
and even worse, a second flatpak update still reveals several obscure errors about EOL of platforms and SDKs, which were apparently not corrected by the successfull previous update:
$ flatpak update

F: ops remaining after sort, maybe there is a dependency loop?
Nothing to do.
I do not know which apps depend on these, neither how I could find out more info about the suspected dependency loop, nor which apps I should therefore deinstall or forcibly update …
In order to have working app-center again, you will have to uninstall the flatpak bundles that you might have installed earlier (This is temporary, until we ship a fix in next OS update).
Open Terminal
flatpak uninstall -y com.rstudio.RStudio
flatpak uninstall -y com.microsoft.winfile
Restart system and see if app-center works. Let us know.
Thanks.
This is quite sad, since I need both, RStudio and winfile.
RStudio is currently very difficult to rebuild and I still have not yet solved my need for a Win32 executable, which I need urgently. But I’ll try …
Maybe I’ll have to use the fedora image in Toolbox/podman to install RStudio & Wine.
Update: yes, after uninstalling winfile & RStudio and reboot, AppCenter does not crash immediately anymore, but when I choose updates, there is a strange message:
“Sorry, something went wrong: Remote “gnome” not found”
Which appears to be caused by the same problem as found by flatpak update above in message #3 …
We are resolved the issue internally. Next OS update(scheduled in Feb’s second week) will include the fix, so that your bundles are working again without crashing the app-center.
… message:
“Sorry, something went wrong: Remote “gnome” not found”
although App center does not find updates, a flatpak update finds 13 necessary updates and in the second run the same errors as in my post #3 above:
$ flatpak update

I still do not know, which installed flatpak needs the Remote “gnome”, which cannot be found.
as far as I remember, I never installed GNOME Builder
thanks for the suggestion. After successfull uninstallation – there were no further dependent installs – I proceeded with uninstallation of the apps, which had these obscure missing metadata messages (frostwire, freecell solitaire, videonet, and weather), and additionally org.freedesktop.Sdk.Extension.openjdk9. But still there remain the following messages:

Nothing to do.
trying to uninstall org.kde.Sdk offers me a selection of 5 different versions and asks me, which I want to use. I chose first 5.9 and 5.10 in a second run.
Checking the output of flatpak list I see apps, which are installed in different versions. Is there an option to automagically remove the older/outdated versions? I tried a flatpak repair, but apparently this does something different. flatpak repair results in around 20 error messages similar to
Object invalid: 85d04a234d7ff52a65cfae1781a3d48015f33513c9005f3a1f5285bffce76ff5.file
when verifying eos:os/eos/amd64/eos3a and five similar ones when verifying ostree/1/1/1 …
I don’t have any idea, if this should be corrected, neither how to correct these.
Finally, flatpak update now complains:
Looking for updates…

and I don’t know, what to do. Any help is welcome.

This should remove any unused runtimes on your system: $ flatpak uninstall -y --unused
as far as I can see release 3.7.7 is out, but my system does not update to it. There was an alert box that there is an OS upgrade available, but despite two reboots I still find that my system is 3.7.6
