I can't get it to open.

I install the flatpak. I click open. I get error message "ldconfig failed, exit status 256". I have no idea what this means.

I would like to add that I've tried reinstalling it multiple times, and it seems like a different error each time. When I tried running it from the console (I used the flatpak), I get the following message:
