Desktop app crashes on startup loading video thumbnail

[kachapman]

I am on the beta 1.15.7.0 flatpak (it started on stable branch). When loading the desktop app, it immediately crashes. It appears to happen when loading the thumbnail of a quicktime video. I wiped out the data and reinstalled, then disabled thumbnail preview in settings. It worked until I tried loading the quicktime video manually.
Here is the error output when running:

flatpak run app.bluebubbles.BlueBubbles

I have tried several ideas from an LLM, to no effect:

sudo apt install libmpv1 libwebkit2gtk-4.1-0 libgtk-3-0 libnotify4 libappindicator3-1 libsecret-1-0 libgstreamer1.0-0 libgstreamer-plugins-base1.0-0 libgstreamer-plugins-good1.0-0

flatpak run --env=LIBGL_ALWAYS_SOFTWARE=1 app.bluebubbles.BlueBubbles

I also tried running from the tarball and got this:

~/Downloads/bluebubbles-linux-x86_64$ ./bluebubbles
./bluebubbles: error while loading shared libraries: libmpv.so.2: cannot open shared object file: No such file or directory

I am running Pop_OS 22.04 LTS on a desktop with AMD Ryzen 9 6900HX and integrated AMD video.

Thanks for all your great work on this project.
