Unlike a standard "crash," this specific error is a safety check built into the emulator. RPCS3 is mimicking the PS3’s sophisticated security and data integrity verification. When the emulator attempts to load the EBOOT.BIN (the executable file of the game) or access specific assets (like .SELF or .EDAT files), it runs a checksum or decryption routine.
Your game files didn't corrupt overnight. Your cache did.
