Elden Ring modded regulation issues.

I've been trying to get elden ring to launch with small mods I make through smithbox (nothing quite seriously big, just param edit), but every time I try to launch it through modengine it gives me the "save corrupted error" even after fresh installs, no cloud saves on, and currently on version 1.16.1.

The main regulation works just fine, but it only if I try to use a modified regulation file.

Anyone has this issue or have found a solution to this?
