Camera and audio permission issue

[VarshaMenon]

Video calling feature was working perfectly with webview until almost 3 months ago. Recently it's not supporting camera and audio functionality, even browser and application have both of these permissions. Would like to know is it because of any recent update with webview or chromium or with anything else, as it was working properly before.

Manifest permissions:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.VIDEO_CAPTURE" />
<uses-permission android:name="android.permission.AUDIO_CAPTURE" />
<uses-permission android:name="android.webkit.resource.AUDIO_CAPTURE" />
<uses-permission android:name="android.webkit.resource.VIDEO_CAPTURE" />

Please anyone respond to this issue, and thanks in advance. Attaching the screenshot for more information.
