Using the latest bugfix-2.1.x (320e002) with matching bugfix-2.1.x Simulator configs, I can confirm that the simulator crashes out under Windows 10 x64 (22H2 / OS Build 19045.4412) as well as macOS Monterey 12.7.5 when POWER_LOSS_RECOVERY is enabled.

fatType_ is not yet initialized

Ahh. That would explain why it boots/works fine if you've generated fs.img & have it loaded.
