Capacitor 2.4 setup on Android exceptions/errors

[kstearns]

I'm trying to convert an existing Angular 9.1 / Nx 9.6 / Node 10.16 PWA app to a Capacitor 2.4 app.
I used @nxtend/capacitor to create a new "apps/controller-cap" based on our existing "apps/controller" PWA app.

The Nx and Capacitor CLI commands seemed to work fine (at least after upgrading from Nx 9.0 to 9.6), but when I try to launch the Android app in the Android simulator (with no changes to Android project generated by Capacitor), I get a splash screen followed by a blank screen.

Logcat shows the following 2 errors - not sure which is the critical failure, or both :

1. I/zygote: Rejecting re-init on previously-failed class java.lang.Class<androidx.core.view.ViewCompat$2>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;

2. E/Capacitor: Unable to open asset URL: http://localhost/controller/polyfills-es2015.8833204e9116bec07d89.js

I'm an experienced web and Android developer, with some Cordova experience, but brand new to Capacitor.
Any guidance on next steps would be much appreciated - hoping it's a simple/known issue.

Thanks.

Sorry for the initial log pollution - updated with attached log file. Thanks.

Ok, so I think I've ruled out #1 as causing/contributing to the problem by following suggestion in following post to increase minSdkVersion to 28 (probably not acceptable for production, but at least bypasses the problem for now).
android/sunflower#295
Still no luck on #2. Tried a suggestion here that the files might be getting blocked by some new file access permissions, but adding the "android:requestLegacyExternalStorage="true"" to my Activity had no effect.
#2916

Still digging for ideas ...

Updated Android logcat file attached after changing to minSdk 28.
Seems like there are several failures/errors and not really sure which are significant or not ... this is starting to feel very half-baked.
Any ideas on the following would be appreciated as I continue to Google for answers for each:
