PS5 grey screen error after 30 minutes of playing nba 2k23 customer returned it to my shop

Customer said a grey screen appeared 30 minutes into playing NBA 2K my boss wants to throw out the system and I already did a safe mode reboot for system database and system storage fix.
Haven’t opened up the system yet to check for any internal issues, since my boss wants to throw it out.
PS5 system is CFI-1215A, white model disc version

likely hard drop and APU damage. sell for parts maybe
