I tried to use find command to find a file named color.cfg (It is a configuration file for latex) Here is my code:

can see, the screen is clustered with "operation not permitted" error and "Not a directory" error, which makes it impossible for me to search for files that I need.
This solution doesn't work as I have already given the full disk access permission to the terminal. 
1 Answer
The directories look system related so it is expected that your user would not have permissions to read the content. Giving your terminal emulator full disk access will not change that, that would be a massive security risk.
There is another solution which works on every unix based and most other OS:
redirect error output
Usually on unixoidal operating systems you can redirect stderr to a file so that it wont clutter your terminals stdout by adding 2> /somefile.
Example:
sudo find / -name "color.cfg" 2> /dev/null
