Moto G6 plus Bootloader crashed?

I’ve gone through all the steps here, but after sideloading the copy-partitions…zip package, I am not able to reboot into recovery mode. Instead, I get a ‘Bootloader logs’ page (black background, red letters) stating

AP Fastboot Flash Mode (Secure)
No bootable A/B slot
Failed to boot Lnux, falling back to fastboot
Fastboo Reason: Fall-through from recovery mode

Is there any way to start over, or have I messed up this phone?
