Exposure time/ shutter speed is capped

Why is the exposure time/ shutter speed for my phone capped at 1/2 (half a second)? I would like to take photos with an exposure time of up to 30 seconds. Even when installing other apps, like GCam or Open Camera, it is not possible to increase the exposure time. I have an Fairphone 4 with Android 13.

In the screenshot you can see that the exposure time (S) is at the maximum value.

Do you have the same "issue" as me, or know how to fix it?
