Error Code 102:d5a74c31

Mostly the same issue:

I am having the same, issue, but I am unable to download any mods, that are not from Curse forge for safety, and I am less likely to get a virus. I don't know what to do. A few days after this issue, started, my game created a save itself, it has a household with pets in it, even though I have no mods that add pets, or a pack with pets. (I have no packs at all, and I am heavy modded) I tried disabling mods. I think my game might be corrupted. This is happening in all saves. Even old ones, and in brand new ones. I don't know what to do.
