Cannot read from source error AME

I literally have had this trouble just today. It was working perfectly fine yesterday. I tried redownloading it and everything but it still wont render. This is frustrating me since im paying for this app and its not even going to work properly. I have the adobe media endcoder 2020 version, along with the same for after effects so that it's compatible. I HAVE to render my edits through adobe media encoder from after effects or my edit won't have good quality. Now adobe media encoder isn't working and says the error "cannot read from source" very annoying . Someone please help me to fix this error
