Try rebooting phone by pressing power button.

If everything fails, do a full fastboot flash with MiFlash tool, but using the flash_all_except_storage.bat script, that should keep your data intact, restore all partitions (A and B) to stock versions and you can then apply OTA (before or after installing Magisk, but I suggest after installing Magisk so you can test if the guide works fine).

You can find the fastboot ROM here:
