.appx unable to access Files on Desktop or external files ? (Unity)

Hello everyone, We are working on a demo and in our demo with out Mixed Relaity Headset we have some assets Stored within a folder located on our desktop which are loaded into the project later . In the unity editor all is well and the app is able to read the files just fine however when I export the build a bug is occurring as if those files are missing or that path is incorrect. yet like I said in the editor it works perfectly fine.

I've seen similar issues before and it usually comes down to a missing permission or something incorrect in the path has anyone tried something similar and did you have to enable the ability for the .appx build of your project to read external files on the desktop or in an external file system ?

I enabled the Removable Storage capability hoping it would help but it did not . Any and all help / suggestions are appreciated.

 

UWP apps have a restricted file access, so you have to add a capability (if the files are in any of the allowed folders), or put the files into folders that are accessible by default:
