Insufficient Space Error when writing to disk

It looks like a permissions issue. Try restarting your computer, checking controlled folder access, and any virus/security software you have installed.

Gave this a shot but I don't have controlled folder access enabled; the only security software I use is Windows' inbuilt stuff and occasional runs of Malwarebytes that I uninstall between checks. 

I continued scrolling down that support article and tried some of the fixes for disk write errors as well, just running steam/game separately as administrator and that seems to have helped for now, and I even tried just subscribing to like 10 more mods to see if it would trigger the same error but so far so good! 

 

 

I have solved this problem for myself by simply deleting the Klei folder in My Documents entirely and then normally launching Oxygen Not Included. If you have other Klei games, you can probably get the same result from deleting the Oxygen Not Included folder inside of the Klei folder. Make sure you have Cloud saves enabled in Steam! Or backup your saves specifically on your hard drive. 

Edit: Another action I took was uninstalling OneDrive from Windows completely. I am not sure if this was necessary, but try doing this also if my first step doesn't work.
