Mods not working, saying Deployment failed

[wilwhitt56]

I'm new to using vortex , and ive been having a problem adding mods to Elden ring. Every time I try I end up with and error saying Deployment failed, the most likely reason is that the file were locked by external application. I have nothing open that could do this. the Mod is just the Lord of Decay armor. Has anyone else got this and, if fixed, please tell me how you did it.
