App crashes when resumed from background with enableZoom: true

**Describe the bug**
When I start the camera with "enableZoom: true", take 1 photo, put the app in the background and then resume it, the app crashes.

**To Reproduce**
1. Start the camera with "enableZoom: true"
2. Put the app in the background and resume it → App does not crash
3. Take a photo
4. Put the app in the background and resume it → App crashes

If one repeats the steps above with "enableZoom: false" the app does not crash.

**Desktop (please complete the following information):**
- OS: Linux Mint
- Browser Chromium

**Smartphone (please complete the following information):**
- Device: Samsung XCover 7 SM-G556B
- OS: Android

Start by reproducing the Android sequence in the issue: enable zoom, take a photo, background the app, and resume it. Trace the camera resume path and zoom handling around that sequence; done means resuming after a captured photo no longer crashes with enableZoom true, while enableZoom false remains unaffected.
