I recently updated my MacBook Pro Retina Early 2015 to macOS Big Sur Version 11.1.
Ever since then my mac has constantly been overheating and randomly rebooting. How do I fix this?

According to Apple doc, Big Sur can be used on MBP Retina models of late 2013 and after. So no reason not to work.

They also indicate that you need 35 or 45 GB available to update.
Did you get this room ?

How much RAM have you got ?
If not enough (less that 16 GB), that could explain some over activity (but not the crashes).

Otherwise, best is to contact Apple support.
