Now that you've disabled OneDrive, you can fix whatever issues it caused and then test CC. Start with a clean folder: Exit Sims 4 then drag your whole Sims 4 folder from Document > Electronic Arts to your desktop. Launch Sims 4 and start a New Game. Reset your Options how you like them.
Now try copying your most recent save to the *new* Saves folder and see if it works without the CC (but don't save!). If it does, copy the CC over to the new folder and test that. With some luck, you'll have cleared up the issue and won't have to do a 50-50.
And I remembered another thing to check (one I ran into myself last night!). Depending on how you moved your content between computers, you might have ended up with some script files having a ".zip" extension added to the end and messing things up for you. If you uploaded folders online then downloaded them, check for files ending ".ts4script.zip" and rename them to remove the ".zip" part.
