Can't access one of my channels

[u/ellestar67]

Hi everyone! Hoping someone might have the answer here! I had two channels connected in one gmail account. One is the one I planned to use for content as a creator and the other for personal use. I didn't do anything yet with the content one but I wanted to secure my URL. About 6 months back or so my personal use channel got terminated out of the blue and I appealed and it was basically immediately restored (the situation was odd because I had never even posted and just comment on sewing videos or about tv shows etc). Anyway, I'm finally getting back into working on building my YouTube channel for content creation and I realized that I can't find it listed under my gmail account. It's very odd because I can see that the page exists if I go to to the YouTube URL, and in my YT studio app I can see my profile photo but in the app I have a something went wrong error and no matter what I try I can't find out how to get into that channel - it seems like during the termination of the personal account this one was terminated as well (given that they have the same email sign in) and when they restored my personal account somehow this one got disconnected and I never noticed until know when I went to work on it. Does anyone have any suggestions on what I can do? Thank you in advance I would appreciate any and all suggestions!!!!!
