Opening the map editor sometimes resets/deletes everything in the game folder

[XnKradst]

This is a rather inconsistent but very annoying bug that has happened to me for the third time now.
The first two times it happened it was in an older version (38.0), and I was hoping it no longer happens in newer versions... but no, it has happened again in version 38.5, which is the latest.

So basically, sometimes when opening the map editor, there's a random chance that the game will decide to delete everything in the game folder and start fresh.
This makes it a risk to use the map editor because it wipes out ALL of my data, including mods, maps, screenshots, saves, replays, etc.

This is the state of the folder right after it happens, these are all the files and folders that remain:

(Commander_Wars.ini might not be there and is only there now because I opened the exe for a split second, but not sure)

It seems the game is, for whatever reason, initializing the folders and files as if I just opened it for the first time, which deletes everything that was already there in the process.
Apparently no one else has had it happen to them, so I don't know if you can reproduce it, but maybe check if there's anything in the game's code that could've possibly caused the game to do this.

All 3 times it happened, it happens when I open the map editor. This time however, I noticed a long delay between clicking the button and getting to the map editor screen, so clearly, some code is running in the background that "initialized" the game folders.
Once it happens, the map editor will "work", but if you try to press Ctrl+Z to undo, nothing happens, presumably because whatever file stores the previous map states also got deleted.

I'm using Windows 11.

I have a guess what happens but it means basically that win 11 set a falsy temp path which leads to a screw you scenario

So if it's really an issue with Windows 11, and that there's nothing that can be fixed code-wise, then is there anything I can do on my end to prevent it from happening again?

I'll replace the folder deletion which targes CoW's temp dir with deleting temp files trying to target the issue

I know this may have been fixed, but something just crossed my mind...
Could it have been caused by a lack of free space on my drive? It was only around 6GB left at the time, if I recall.
That would probably explain why it apparently hasn't happened to anyone else, as I'm currently running low on disk space.

My assumption is that whatever assigned a temp folder path to be deleted somehow failed, and so it defaults to the game's main folder. But something has to have caused that failure, and low disk space is my guess?
