Try deleting (or renaming) the Documents\PvZ folder and relaunch game. This should default settings.
Still no?
Try forcing borderless mode: ((pretty sure this is right numbers.. been awhile))
C:\Users\<USER>\Documents\PVZ Garden Warfare\settings\PROF_SAVE_profile
Borderless:
GstRender.FullscreenMode 2
GstRender.FullscreenScreen 1
=============
Does it seem like the game freezes instead of just not accepting inputs?

Suspect GPU drivers might be causing the freezing (or 3D Property settings in NvidiaCP // Catalyst).
