Youtube Channel Exportation

Recently it seems that I can't access my Youtube channel from my account since it says it's connected to another account. Before I was able to export scores from my main account but a week ago Musescore's uploading process seemed to be broken, so I made a different account to try and fix the issue. It worked, but then I had to get the score from that account to Youtube, so I linked my account there and later deleted the account since I didn't need it. Now I can't connect my Youtube channel back to my main account even though the other one had been deleted already. Is there a way to fix this? Thanks.
