I'm having the same issue, it crashes on exit, and after a scan.

[jessorlisa]

I'm experiencing a similar issue. With a freshly started device and app, I'm able to scan around 20 codes before it crashes. Following that, every second scan results in a crash, producing crash logs that are almost identical to those provided by @Yauheni-Matveyenka.

@jessorlisa If you're up to trying something new, checkout @nativescript/mlkit-barcode-scanning I found it works really well!

[jessorlisa]

@rob4226 switched to mlkit - thanks for the tip.

[andrewm-mitchells]

Same issue here. MLKit also fails to build currently
