Corrupted Save PS4 Slim

I downloaded the game for free from the PSN catalogue. As of update 1.41 I have had 3 instances of save data corruption within the span of 5 hours. Two of which came after the game crashed back to the system menu. The third instance of save data corruption occurred when starting up the game. However… that third instance of save data corruption resulted in the complete loss of my data with no restoration. To make matters worse I had no access to the game nor my psn online storage or any information from any game for that matter until ultimately deleting the game and the supposed corrupted save file. I’ve completely lost all game progress.

I am uncertain of any particular elements that may allow one to reproduce the issue, but I atleast recall what I was doing during each instance of crash/data corruption.

Crash+data corrupt 1) Was fast traveling from a hideout in the northwest corner of the farmlands towards a bunker in the south. (Possibly the first bunker you encounter through main story missions). Crashed about 3 seconds after initiating fast travel.

Crash + data corrupt 2) Was assaulting a FNIX base somewhere in the farmlands and crashed when causing a chain reaction of machines to explode around their spawn point and mines.

Data corrupt 3) Happened upon reaching the main menu. The file corrupted, couldn’t fix my save and wouldn’t let me play due to repeated error messages.

As an extra note: All inventory items, loot and storage have become improperly displayed. I am not sure if this is a result of the corrupted data or not. Example: I open an ammo crate. All the item images are of a simple first aid kit and the number is always inaccurate. The information becomes properly displayed only after interacting with one item and moving the cursor.

This happens to everyone since the update.
It’s been reported quite often now like that https://youtu.be/LTijy_rG5pM?si=LLjTbgVcGu1e9S52

Regarding the crashes and save data corruption:
Is the game installed on internal or external memory?
