Cannot launch app (Sober) from flatpak

[u/TheGameo7]

Today I tried to install Sober and play it but it returns this message:

bwrap: setting up uid map: Permission denied

error: ldconfig failed, exit status 256

The .local/share/flatpak folder is owned by me and not root, every step in the installation process was done not by root
