Steam isn't opening

**Distribution name and version where applicable**
Ubuntu 24.04

**Flatpak info**
Flatpak 1.14.6
default
host

**Problem description**
Quando eu tento abrir a Steam, um erro é retornado. Já tentei fazer o que está descrito no artigo https://github.com/flatpak/flatpak/wiki/User-namespace-requirements, porém não adiantou.

```
$ flatpak run com.valvesoftware.Steam
bwrap: Creating new namespace failed: Permission denied
error: ldconfig failed, exit status 256
```

**Does this issue reproduce with native Steam**
Only with .deb and flatpak
