Reading NFC card while connected via USB to a computer and to qFlipper leads to a OOM Crash

[hac-v]

Describe the bug.

Firmware version 1.3.4.

$SUBJECT.

Reproduction

1. Connect to a computer via USB cable;
2. Select "Read" to read an NFC card;
3. Observe the "out of memory" crash message before anything else appears on the screen.

The reproducer is reliable for me.

[see log below] ~~However, when I use the dev board to collect debug logs, the crash does not happen. I am not sure of the reason (I'm new to flipper, got mine two days ago). If there are better ways to collect this other than connecting the dev board to FlipperZero and via USB to a computer, let me know. ~~

Target

No response

Was able to reproduce by tapping buttons on the UI.

Greetings! Sadly this is expected as we ran out of memory, NFC is one of the most memory intensive apps. I will investigate, since it should give you a prompt on app start to reboot when memory is too low.
