AppCenter crashes shortly after launch

### What Happened?

When launching AppCenter from the Dock, it starts up, starts checking for updates, and while in the “Getting app information” phase, crashes.

When launching from the Terminal with `io.elementay.appcenter` it exhibits the same behavior, but upon crash one can observe an error message akin to the following:

`(io.elementary.appcenter:4104): GLib-CRITICAL **: 11:46:44.226: g_strsplit: assertion 'string != NULL' failed
Segmentation fault`

An attempt to get things fixed by running
`sudo flatpak repair`
unfortunately didn’t lead to different outcomes.

### Steps to Reproduce

Launch and get the crash

### Expected Behavior

Launch and no crash

### OS Version

7.x (Horus)

### Software Version

Latest release (I have run all updates)

### Log Output

```shell
(io.elementary.appcenter:4104): GLib-CRITICAL **: 11:46:44.226: g_strsplit: assertion 'string != NULL' failed
```
