Which config file is used by w3wp.exe process in an application?

I have a issue where I get SerializationException The internal array cannot expand to greater than Int32.MaxValue elements..

The solution to this is adding the below line in the config file.

<AppContextSwitchOverrides value="Switch.System.Runtime.Serialization.UseNewMaxArraySize=true" />

But the problem is even after adding this in web.config file the issue is not getting resolved. .Net version is 4.8 and also restarted the IIS after making changes.

I have used procmon to see the config file used by the w3wp, it shows the config file path as: For some process: C:\inetpub\temp\apppools\Archer\Archer.config For some other process: C:\inetpub\temp\apppools\DefaultAppPool\DefaultAppPool.config

Please help me to know which configuration file is used by the w3wp.exe process as it got reported that particular process.
