Steam Mobile app not requesting camera access on iPhone

Hello, I want to use the camera to scan a QR code via the Steam Mobile App, but the camera won't open because the Steam Mobile App doesn't ask for camera access permission.

When I look at Access in Settings, it's not given manually.

The Camera option is active in the Screen Time section.

I restarted the device using Volume Up - Volume Down - Side Button.

I reset the network settings.

I uninstalled and reinstalled the app.

I reset the phone again.

However, none of these options worked.

The question is: How can I grant camera access permission to the Steam Mobile App?
