Mortal Kombat vs. DC Universe [BLUS30246] no longer loading

On SteamDeck versions after rpcs3-v0.0.25-14519 are no longer loading Mortal Kombat vs. DC Universe [BLUS30246] 

rpcs3-v0.0.25-14519 and prior versions loaded fine and were playable.

Log file attached from latest build rpcs3-v0.0.26-1-6532d2b6

The log file you tried to attach can not be opened in a text editor, so it's probably corrupted

Either way, rpcs3-v0.0.26-1-6532d2b6 is not an official build, it's probably the Flatpak, you need to use official builds to ask for support
