Error Response: Error appears when transferring data between PS4 and PS5
Solution: If you have our PS4 and PS5 connected to the network wirelessly, try instead using a wired connection using an ethernet cable to transfer your data. Re-attempt the data transfer by going to Settings > System > System Software > Data Transfer. Unplug your PS5 and plug it back. To turn on the PS5 into Safe mode, Press and Hold down the power button on the Playstation 5, until the console beeps twice. Connect your controller with a cable and select "Rebuild Database". If this doesn't solve your problem, try contacting Sony directly or a video game repair shop for further help. Please post below if you were able to solve the issue yourself to help others.
