Can't open .mcaddon through minecraft using files app

I tried restarting my device, but I can't open .mcaddons or.mcpacks through the files app, even though I could to it once. It worked with one I got through an app and it opened through that app, but I can't open it with files. It for some reason says flipaclip when it doesn't even support MC files

 

I'm using Pixel 6a
