[com.starlingbank.android] Starling Bank crashing on login verification video

Affected app
Name: Starling Bank
Package id: com.starlingbank.android

Describe the bug
When logging into an existing account on a new device, verification is required by recording a video of yourself saying a provided phrase. As soon as "Start Recording" button is pressed, the app crashes.

To Reproduce
Steps to reproduce the behavior:
0. Have an existing account with Starling Bank;

1. Open app after installation on new phone;
2. Click on "Log In";
3. Enter account mobile number and click "Continue";
4. Insert verification code sent by SMS and click "Continue";
5. Enter password and click "Continue";
6. Enter full name and click "Continue";
7. Click "Start Recording";
8. App freezes and eventually crashes.

Expected behavior
Should be able to make recording and submit to continue verification and logging in.

System
Device: Xiaomi Mi 9T Global (davinci)
Android Version: 11
Custom ROM: MSM-Xtended 5.0 (20210205)

microG
microG Core version: 0.2.17.204714
microG Self-Check results: All ticked

Additional context
Will require an existing account with Starling Bank, something I can't imagine many developers have access to. I would be happy to assist however I can.

Start by reviewing issue #1411 and reproducing the Starling Bank login verification flow on Android 11 with microG 0.2.17.204714, if suitable test access is available. Investigate the freeze and crash when Start Recording is pressed; done means the video can be recorded and submitted so login verification continues.
