PS4 error code CE-36329-3?

I have the problem that my PS4 Pro switches itself off and on again and again and shows me the error code "ce-36329-3". I also have the feeling that my PS4 Pro is a bit delayed in everything (booting up, menus, Games etc.) I'm also kicked out of the game in Star Wars Battlefront II, for example, and the above-mentioned player code is displayed to me, I have already uninstalled and reinstalled the game and it also seems to work in arcade mode for games like COD: Warzone is again the problem that my PS4 pro does not grab the graphics or that they are displayed very "contoured", I have already informed myself about the code and have tried everything possible, system re-launched (initialized), system software updated etc.
Do you have any idea why that could be or what I can do about it?

Make sure you have the latest version of the system software installed by going to Settings> System Software Update. The system will then restart.
If you can't access Settings, please update your system software using option 3 in Safe Mode.
If the error occurs again, please back up your saved data and initialize the PS4 system by going to Settings> Initialization> Initialize PS4 or using option 6 in Safe Mode.
If the error persists, please contact PlayStation support.
