SuperNight mode does not take photo (no output) — /e/OS 3.4 FP5

OS: /e/OS 3.4-a15-20260114569178-official-FP5
Stock FP5 Camera app version: v6.00.04.0038.18.0

Device: Fairphone 5
com.fp5.camera

Description:
When I try to use the SuperNight mode, the camera app behaves normally (no crash), but the photo is never taken. No error message is shown; the shutter/button appears to activate but the capture never completes and no file is saved.

Steps to reproduce:

1. Open the Camera app (stock FP5 camera).
2. Select mode: SuperNight.
3. Point the camera at a low-light scene.
4. Press the shutter button.
5. Wait — no photo is saved and the capture never completes.

Expected behavior:

• The camera takes the photo (or shows an error) and saves it to the gallery.

Actual behavior:

• The capture never completes; no crash, no error message, and no photo file is created. When I open another app and go back to the camera app after a while it says something like ‘This is takes longer than expected. Do you wanna close the app? ‘

Frequency:

• Always

What I already tried:

• Rebooting the device
• Clearing cache & data of the Camera app
• Resetting camera settings
• Turning off the stock FP5 camera and turning it on again
• Testing with another camera app (Default Camera app (open camera). Gives the same problem.
