OBS: Failed to open NVENC codec (NVENC already Installed)

I'm getting following error in OBS when I try to record with NVENC:

Its official OBS flatpak package. What might be the problem?

Re: OBS: Failed to open NVENC codec (NVENC already Installed)

The entire point of flatpak is that all those libs should be irrelevant... Have you tried reproducing with the repo package? Which nvidia driver is installed in the flatpak?

Re: OBS: Failed to open NVENC codec (NVENC already Installed)

I could get the app work with the repo package due to some QT error.
OBS package works fine except this nvenc error.

These are the drivers installed in flatpak

flatpak list | grep nvidia
nvidia-545-29-06    org.freedesktop.Platform.GL.nvidia-545-29-06        1.4    system
nvidia-545-29-06    org.freedesktop.Platform.GL32.nvidia-545-29-06        1.4    system

Edit: I fixed the QT issue. It was easier than fixing the problem with the flatpak build.
