Same issue but kind of different. After updating Big sur, I can't fully charge my mac even though I always charge it. It shows that the battery is 80%. Yah, it stops here. I even don't know why.
I tried to update the new version of big sur, but I failed because I met new version installment problem. So it seems like dead loop. I regretted updating big sur from Cato.
