Rain World thinks save + certain backups are empty after crash during saving

[white oar]

When I was playing through the Saint campaign (with mods, mind you) to get the tokens I haven't gotten, I navigated to one of the rooms in the starting region with a shelter and pipe entrance being entered fram below, one from above and I think one raised but sideways, with several pits that I think is somewhat close to a gate on cycle 2. When I decided to go past the shelter and to another room, the game instantly closed. No unity crash window, nothing.
The next attempt, I went to the same room and tried to use the shelter in the room so if the game crashes again, I can easily keep trying things to go further. However, when sleeping (specifically when the screen faded to black), the game instantly closed again.
After reopening again is when rain world thought my save file was empty.
This bug has happened multiple times, in and out of modded campaigns (however if an unmodded campaign, it seemed to always be the saint campaign)
Additionally, when this type of glitch happens, it also causes several backup entries created before the glitch (and therefore working fine normally) to also be mistaken to be empty.
However, if I load one of these "empty" backups and open the sav txt file in a text file (or from the backup's folder itself), it is shown to very much not be empty, despite the game's claims.
ConsoleLog also shows the game claiming these saves/backups are """"empty"""".

I cannot simply start over, as I have not finished with the watcher campaign and have already gotten all but one ending (a pre-1.5 one). and this has happened several times before, so I am in need of some sort of way to fix this.

This happened on a Steam Deck, and there were no exception logs.
The files uploaded on this part are the latest backup, which the game thinks is "empty".

(continued in next message)

One thing I have noticed is that the most recent "non-empty"/working backup is double the size of the most recent non-working backup, yet the backup immediately before the most recent non-working one is a similar size to the working save, despite the game also claiming that it is empty.
I have also found that it seems the backups that the game says are "empty" seem to have data related to the saint campaign, even before I started the campaign, while the latest working save doesn't.
Additionally, it seems that while the game things some backups are empty, going to these backups and manually creating a backup of them doesn't create an empty backup, and has the actual data inside.
Both of these I found by opening the sav files in a text editor.
These next saves show the latest working save, for reference, which oddly puts my watcher save in shaded citadel in post final ending state despite me never actually going to shaded citadel after going to the watcher-specific regions and leaving the vanilla regions behind.

And this is the save just before the latest non-working save, for additional reference.
Note the sav files on the main post as well as this one has data pertaining to the saint campaign, while the first reply with the working save doesn't.

This type of crash into saves being seen as empty has happened several times before, including before the watcher DLC initially released, and would very much like a way to undo such a thing. It seems every time that such a thing occurred with a non-modded slugcat, it was always saint.
