Hi @oswajas
according to your crash report this is within Android itself, see

Caused by: java.lang.IllegalArgumentException: Unsupported ABI: null
at dalvik.system.VMRuntime.getInstructionSet(VMRuntime.java:370)
android.webkit.WebViewFactory

There is likely nothing we can do about this from an app's perspective. Could you check if you can install the webview update from Google: https://play.google.com/store/apps/details?id=com.google.android.webview this should replace your system web view with a actual version which might solve this matter for you.

[oswajas]

Updating Android System WebView solved the problem.

@oswajas Glad to hear this solved the issue 🚀
