I can't help but can sympathize. The same thing happened to me yesterday - could read the SD card and then suddenly couldn't (tried cleaning up the SD, unplugging, etc). On top of that, it wouldn't let me wipe the current seeds. I tried multiple times in a few different ways, both before and after the firmware update. After all the warnings that I agreed to, it just announced "aborted" and that was that. I don't have much of a stack so wasn't dealing with the panic of many folks, but for me it was multiple Coldcard failures on top of the entropy problem.
