Some mods not showing up in game
caity2805 It does look like you've done things correctly, but please confirm that the game is still reading this folder now that you've changed some settings. The DeviceConfig file should show a time stamp from precisely the last time you opened the game. If it doesn't, the mods are in the wrong folder, as in, what the "right" folder is has changed.
If the mods are in the correct folder, it's worth testing with OneDrive out of the picture. You can set up a new, local, admin Windows account, local meaning not linked to your Microsoft account or any email address. Without that link, there's no way for OneDrive to touch your files. Or you can get rid of it on your main account, as described here:

It's your choice what you want to do; the test is valid either way.
