White Screen on android that wasn't there before

Capacitor
#1

For my app, I am using Ionic 5, Angular 11, Firebase, Capacitor.| My app was working on android before the update. Angular 11 came out, and my project was running on Angular 9. So I carefully followed instructions on the Angular website about updating Angular. I updated Angular and got a ton of new errors saying my dependencies old. I deleted them and re-installed them. Then, my app started to work on a web browser, and I didn’t test it on the phone. I coded some stuff, and it is working well on the web without any error. But when I tried to run it on android, it is not working. I also commented on the new code to test if it is a problem, but it seems the new code is not related to it. Below is all the errors on Android Studio

:wave: This sounds similar to this issue

Basically, chrome 83 has a known bug regarding this issue. Angular changes something in the release that made the bug surface and are aware of it.

A few steps to work around it for now:

  1. Upgrade the system webview of the simulator.
  2. add "aot": true to your build settings in your angular.json

@mhartington facing a similar issue but I haven’t updated the project just the global version, I have no idea what to debug because just like above, it’s working fine on Web but not on Native. Here’s the log from my Android Studio:

Also - I’ve implemented the suggested workarounds above as well, still nothing.

Please help - sort of urgent as this build contains fixes for the production build but I can’t ship because of this issue.

Best,
David.
