That's not a crash exactly. 
This happens if the portal fails in the request to "CreateSession". Can you check the portal logs? 

Can you confirm if any other screen recording (such as OBS) works using the portal?

Thanks, my portal did not work. I fixed it and xwaylandvideobridge started working too.

I'm having the exact same issue (Also on hyprland and NixOS) but can't find the logs you are referring to. Are you talking about the xdg-desktop-portal-hyprland logs ? I tried getting those with
```
journalctl -u xdg-desktop-portal-hyprland
```
but it returned no entries. How did you manage to solve this ? Thanks in advance.

I've added this to my home manager config:
```
    xdg.portal = {
      enable = true;
      extraPortals = with pkgs; [
        xdg-desktop-portal-hyprland
      ];
      configPackages = with pkgs; [
        xdg-desktop-portal-hyprland
      ];
    };
```
and it started working. Hope it helps.

Thanks, this snipped solved it. Simply adding the xdg-desktop-portal-hyprland to home.packages was not enough, I had to configure the xdg module. 
Many thanks :)
