Tried some old Far Cry 4 tweaks and it eliminated the freeze issue.
In Documents folder/ my games/ far cry 5
Open the GamerProfile.xml file with Notepad Find GPUMaxBufferedFrames="0" and change to GPUMaxBufferedFrames="1"
and also change DisableLoadingMip0 ="1".
also possible to try this if an nvidia card is being used
The Fix
Go to Nvidia Control panel and set Power management mode to use prefer maximum performance and change maximum pre rendered frames to 3.
