Game frozed when i use the Recycling Station - Support and Bug Reports - Generation Zero Forum

impossible to play this game for 2 months even after deleting the world then the character and finally deleting the game and re-downloading. the game froze on all the storage boxes and now on any new part by opening the first storage box in the church. Will this game be playable again on PS4 or not? gz vers:1.44 with all Dlc. ps4 ver: 11.02
Haven’t played on PS4 since the latest update.
Maybe I’ll give it a try tomorrow, just to feel the pure difference to playing on PS5 
Before the update everything was fine for me. Well, not everything (airfield roof, safehouses missing), but the game never crashed.
Is the game installed on internal memory or on an external storage?
Are you connected to internet by cable or WiFi?
