Those EXT4-fs write access unavailable errors look spooky. Should probably do some standard Linux FS testing (fsck)
I’ve not had to recover anything from a raspberry pi SD card, but in the case you start from scratch - and considering it’s upset at write access - you may be able to plug it into another machine and at least salvage bits of its configuration that way.
It was not someone from management who said this, it was one animator on the team who had already stopped working at Firewalk and was on Twitter referencing people hating on the game in their twitter thread where they were celebrating the work they and their teammates had done.
Still, sounded quite general and is an unwise thing to say publicly.
