Safari in Big Sur

Hi, practically Safari 14 on my MacBook Pro 2020 is unusable.
I also tried to delete the plists and open it by holding down the shift key.
Nothing, very slow.
Ideas?
Thank you
Assuming you are referencing Safari 14 on macOS 11 (Big Sur).

Can confirm. macOS 11.0 Beta (20A5323l) -- Safari crashes almost instantly after launch. Solved by removing the offending alias file found in /Library/Developer/PrivateFrameworks/CoreSimulator.framework

Moved the alias file CoreSimulator to the trash. Safari launches without crashing. Put back alias file to referenced location, Safari crashes almost instantly after launch. 

Snippet of Crash Report:
Dyld Error Message:
Symbol not found: launchpathforuserservice4coresim
Referenced from: /Library/Developer/PrivateFrameworks/CoreSimulator.framework/CoreSimulator
Expected in: /usr/lib/libSystem.B.dylib

Thank you everyone's participation in this thread.
