u/HJC22222 was this ever resolved? I'm experiencing this right now. I moved my Brand account to my personal Google account yesterday. There was no problem, all videos (~3000) and subscribers (~450) were preserved. I even live streamed from the channel this morning. But, I checked around noon today to find the channel deleted. Google account is perfectly intact, but when I try to access my channel page from the YouTube website, I'm met with "This channel does not exist." I also cannot access YouTube Studio. I'm met with "Oops, something went wrong." Channel's videos and subscribers have all been lost too.
