Summary
Hello, I’m using Unreal Engine5.7.4 launcher build, CL51494982,
with the matching PS5 Platform Extension copied into Engine Platforms PS5. Prospero SDK 13.00.00 is installed. The dev kit is activated and shows in Sony Target Manager. In Unreal, under Platforms SDK Management, PS5 shows ‘Error info, the platform SDK status was not returned from Turnkey.’ The output log includes, ‘failed to load module PS5 target platform, reason equals file not found.’ Turnkey itself runs successfully. Could you advise why the PS5 target platform module is not loading on this launcher setup?
