Search for files in ~/Library using Finder/Terminal/Spotlight not working

I was navigating using the Finder to ~/Library/Preferences and I can see visually that there is a file. However I cannot search for it in Finder, or in Spotlight or using the Terminal (sudo find . -type f -regex "com.") I allowed Terminal to have fulldisk access.

It is very strange and quite frankly seems to be a huge privacy and security issue as I wonder what would happen if an file like a virus, ****** etc is there, but I cannot find it, but could find it by visual inspection (quite a crippled way to find such).

I do not know how this way one can ever trust the system!!!!!

Can this be changed!!!!!

As a user want to have the FULL ACCESS to my computer!!!!! PERIOD!!!!!

I do not appreciate that especially after all this loops to give full disk access to a program like Terminal cannot have full access to my own computer and folders/files like this!

Is this a bug????? Or is this just a feature (Please get rid of it if it is just a feature, it is a very very bad and UNWANTED FEATURE, I do not know who in his right mind want it)????
