Corrupted Save Error when combining Mckenyu’s Moveset with Seamless Coop

Hi everyone, I need some help!

I’m trying to run Mckenyu’s Moveset alongside Seamless Coop, but I’m running into a "Save Data Corrupted" message. Here’s what I’ve done so far:

1. Tested the moveset mod via its own launcher and it worked perfectly with my base game saves.
2. To use it with Seamless, I moved the mod files into the mod folder of Mod Engine 2 (as I usually do with other mods).
3. Every time I try to launch the game through Mod Engine 2 now, it gives me the "Save data is corrupted" error.

I even tried deleting my Seamless Coop save files (.co2), but the error persists. Does anyone know why this is happening or how to bypass the corruption check when using Mod Engine 2 with Seamless?

Thanks in advance!
