[Treble-Enabled Device Development A/AB ROMS] mgillespie:
Never had any problems with my Huawei Mediapad M5 uptil now, every month I updated, just flashing the system in fastboot and it's been fine. This time however, going from 109 to 110, every app just crashes, even system apps like settings.... :( Using system-arm64-aonly-gapps-su.img

A couple of stack traces from logcat, which may be related...
