Flatpak version crashes right away

[IasG]

I just installed the flatpak version of shotcut as the snap version didn’t work (i posted about that here: Shotcut does not start with “Free(): Invalid Pointer” error on Ubuntu Studio 18.04 LTS ), but as soon as i launch the flatpak version this is what i get:

/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=shotcut --file-forwarding org.shotcut.Shotcut @@ %F @@

I am not very good at this, so is there someone who knows what my problem is?
Thank you in advance

This is probably a problem with the flatpak version on your system. As @pete has mentioned in the other thread, you need to give your flatpak version (not Shotcut version, which we already have):
$ flatpak install flathub org.shotcut.Shotcut

[pete]

@IasG I guess you have a Nvidia card? The host and sandbox OpenGL driver don’t match. How did you install Shotcut? What’s you distrubtion?

@shotcut Maybe you can open and pin a topic about flatpak with a link to the Flathub issue tracker?

flathub/org.shotcut.Shotcut

Thank you for your answers - since I was in a hurry with my project and with all my files on an external drive I just made a fresh install of Ubuntu Studio and installed the snappackage again and removed the csladspa file (i had tried this with no effect prevously) and it worked all of a sudden.
Therefore I dont recall what flatpack version it was, but thank you for your responses!!

I’m under the impression that you think, Snap and Flatpak are the same thing. This is NOT the case!

[IasG]

No i am not - I have linked this post to a different post where i talk about the snappackage i tried to get to work and then i created this post about the flatpack not to mix them uo
I then went back to the snap-version since the flatpack wouldn’t run on my system (i am uncertain as to why) and that is what i am referring to in the other answer @pete
