For now, you can do one of two things:
Immediate Fix:
A patch was released recently which has caused this issue (v1.03). Due to this, Frictional Games rerolled the latest available download to v1.02, however, due to how PlayStation works, if you have already downloaded 1.03, it will not simply revert back. Uninstalling and reinstalling the game will fix this issue, and will not delete your progress.
Or wait for a 1.04 patch, to be released soon.
Frictional has commented on this issue and have also noted it on their official Facebook and Twitter accounts.
I'm also going to lock this thread, as it is a duplicate of this one:
