Here's the picture attached. I have no other mods that use ALT P. As soon as I press ALT P again, when LCPDFR is turned off it goes back to normal. Any help is appreciated. Thanks.

 

Your 'definition' has been turned off. To turn definition back on, go to graphics settings, you'll see the definition switch at the bottom.

Nah,  its just because the shortcut key for toggling the Defenition ON or OFF.is key "P" so you could just press it again to toggle definition "ON' or to back to "Normal" that you have said. In fact you could toggle it in the Graphics Tab in the Menu

You could just press P afterwards and it will go back to normal

If you have trainer installed this May be a keybinds. Try and change the Keys of your trainer(if you have it) and it May work

How would this help? The only thing the OP needs to do is to press 'p'. 

Yes i know. But i experiened diffuculties with it. Might be what happend to him?

The issue the OP explained was that the screen was blurry, that is caused by pressing the button 'p'. Not bashing your reply, it's just that 'p' is the cause.

All that needs to be done is press "P". This is not an issue with the trainer at all. OP said he doesn't have any other mods besides LCPDFR that use ALT+P.
