This issue seems to occur when navigating through and selecting customization options too quickly in a short period of time. It can be resolved by deleting your save data for Predator: Hunting Grounds.
Deleting your save data will not impact your in-game progress and unlocks.
However, you will have to recreate your loadouts.
