How to handle dirty shutdowns?

[ironumbrella]

For reference, this was the post that prompted the concerns above:

Hard shutdown broke my system

After a hard shutdown, my Qubes OS 4.1 has broken. It did not allow me to start any VMs with the error something like with different numbers. After trying these commands (I shouldn’t have done it!) I completely broke the boot and it is now stuck at Job is running for LVM event activation on device 253:0 (10min 10s / no limit) Finally, as I feared, I reached a point at which qvm-volume-revert cannot save me Please help.

And btw, why can’t I edit my post? I coulda sworn I was able to do so before.
