Invisible/Partial Enemies + Items Falling Through Map + More

I started playing Dead Space a few weeks ago and have run into major issues as I progressed from Chapter 9 through Chapter 11. The issues began early on with one enemy bugged in Medical, then got worse after finishing Chapter 9.

The issues are as follows:

1. Most enemies are now showing as body parts (floating bellies or thighs) or are completely invisible. This began with the first enemy in Medical that appeared as only floating thighs, but the game seemed normal after that for the most part, except for rare occurrences. After completing Chapter 9, I backtracked to grab collectibles only accessible with the Master Override, and that's where it become a major issue. Through the entirety of Chapter 10, enemies weren't appearing properly, except for a rare few. This includes the Hunter appearing as a set of thighs. Furthermore, enemies were unable to harm me, and there are a select few enemies that I couldn’t harm as well. Once in a while, an enemy would be able to grab me, then return to their state of invisibility.
2. Items dropped by enemies and in containers/lockers are falling through the map. This began for all items at almost 100% rate since going to Medical at the beginning of Chapter 10, mentioned above. Furthermore, this includes Nodes and batteries for doors/elevators. I also feel that some of the lighting has disappeared in certain areas as well, which is strange. I believe the lights may be falling through the map, specifically lanterns and similar lighting devices.
3. Every other save file after Chapter 9 leads to loading into a black/blank screen where the game is unplayable. I've had this happen a few times, regardless of how it saved (i.e., auto, manual, or overwritten). I am only able to continue playing if I use an older save.
4. While in Chapter 11 attempting to move the Marker in Cargo Bay, it gets stuck on an invisible object. I was unable to continue the story due to this, no matter how many enemies I killed while waiting for the Marker to move.

These issues have been occurring for 7 months after release, and have been reported as early as January/February of this year by other gamers, so I wanted to check if there is any progress on a patch. Thankfully, I have a save right at the end of Chapter 9, so if it is ever fixed, I hope to resume my playthrough. Since I was Achievement hunting + gathering collectibles, restarting is not an option, especially at over 12 hours into the game.

To save time, I will answer a few questions by EA Support to other players with similar issues here:

1. A majority of the issues started occurring on 08/28/2023 on the most up-to-date patch of the game.
2. I am playing on Xbox Series X via SSD (not an external USB SSD).
3. I have tried making a new save file, rebooting the game, closing quick resume, and confirmed it still happens.
4. I have tested older saves, up to 2+ hours prior, and ran into the same exact issue each time.
5. I have attempted uninstalling/reinstalling the game.
