Installing on 2017 MacBook Air Mac OS 11.6 - No such file exists

[bluejays-fan32]

I downloaded the patch and followed tutorial form youtube to install, when I search finder for "/System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore" there is nothing there.

Tried continue following the tutorial on installing the patch but I get the error in terminal

__lldb_expr_64/repl.swift:216: Fatal error: Failed to load SidecarCore.

chmod: /System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore: No such file or directory

Any Ideas on why this is happening and how to ensure that the file exists and is in the proper location?
