OBS not running on Linux Mint

[leeran9]

Hello.
OBS does not run on Linux Mint.

Linux Mint 21.3 Cinnamon
Cinnamon version 6.0.4
Linux kernel 6.8.0-51-generic

I have a problem with the old version of obs studio installed as a Linux Mint software manager system package. So I deleted the existing obs studio and reinstalled it with the flathub flatpak version to use the latest version. However, this does not work. When I run it, nothing comes up. It does not work at all. How can I run obs?
Please help.

I found a solution.
KDE Platform Runtime was missing.

flatpak install org.kde.Platform/x86_64/6.6

I solved the problem.
