I had a similar debacle, when I managed to corrupt a btrfs file system to point it wouldn’t mount again…
I was preparing it to have as my main system on bare hardware. I had accidentally mounted the same block device simultaneously in the host and guest: kablamo silent corruption and all 5 hours of progress lost.* :(
*shred the guest VM, host was ok.
I think the difference with Dolphin is that it now emulates an extinct system(s), so it cannot possibly compete with the actual thing. They did have a close call last year, if I remember, and they pretty quickly went into “jettison all illegal shit out of the code base NOW.” -mode.
