Scanning ceases to work

[MarioVilas]

I've encountered this problem where suddenly scanning stops working, not just on my app but on the demo app found here. This is my log output in case this sheds some light, I've not been able to find the cause for this.

I'm running on a Huawei CC9 phone, and Chinese devices are known for not operating correctly with Google stuff sometimes, but the odd thing here is the barcode scanner was working well and suddenly stopped working one day, same device, same APK.

Solutions according to the internet are: clearing your Google Play Services data, reinstalling the app, or rebooting. None of this worked in my case.
