You are not alone! And be alert, because with me these problems caused by the update have evolved into something much worse.
My Macbook Pro model A1990 turned into a brick after upgrading to BigSur. First the screen flickered and the system froze, forcing me to restart. ( several times, day after day ).
Now, since 7 February 2021, the Macbook Pro is no longer booting. Whenever the problem occurred, there was a blowing sound accompanied by the crash. The macbook pro in question was purchased in 2019, new and with a configuration well above that needed for development in javascript using VSCode. After all, how can a system like BigSur prevent a Macbook i7, 16RAM, 512 SSD from doing the same thing that my old Lenovo ideapad Z460 notebook can still do today with an i3 processor and 4GB of RAM?
