Why doesn't Roblox Studio have permission to make autosaves?

I first want to point out that I am sorry this isn't a Lua question, but I have nowhere else to ask this (at least that I know of) so I am asking it here.

I have a game that I opened (Its opened in team create) and I was messing around with some stuff. All of a sudden this message popped up:

Save File Failure

Could not create auto-recovery file. Please ensure that you have sufficient Permissions to path: "C:\Users[my name]\Documents\Roblox\AutoSaves".

I have never seen anything like this before. I presume this appeared because Studio tried to autosave and couldn't access the file. As far as I am concerned, I haven't changed anything to do with permissions or Studio settings. If there is any fix for this please let me know. It's not too important, but I don't want to lose any progress because autosaving didn't work. If It ends up fixing itself I will try to remember to edit this post.

Thanks in advance.
