Controlled Folder Access

I am having an issue on my Windows 11 computer where one of my main folders is continually reset to read-only. I have looked around for a solution and everything that I have been able to try has not worked. One option that I have not been able to do is use the Controlled Folder Access feature in windows. The reason for this is the location to get to this setting does not appear when I go into the Windows Security Settings area. Does anyone know how to get to this setting to see if this is the issue and possibly fix the problem I am having? Or if anyone knows of another way to fix it?
