HELP!! Anyone experience this issue/something similar and/or had it resolved?

Hi, new to this sub and am seeking helpp

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. However, I checked around noon today to find the channel deleted.

The 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."

The channel's videos and subscribers have all been lost..

Has anyone experienced this issue/something similar and/or had it resolved?
