I'm trying to access the File Management through admin and I get a critical error Invalid attempt to call FieldCount when reader is closed.

The error from the event viewer is:

I'm using DNN version 7.4.2. Also, the host file management works perfectly fine.
Does anyone know what is wrong?

Some additional info: I did a clear cache, recycle application pool, and IIS restart. The problem still is not fixed. I'm still looking into it, if anyone has any ideas please share :)

there might either be a file larger than 2 GB or with an invalid size.

Hello and thank you for the reply!

 I'm going to search for a file with very big size, but what do you mean by "invalid size"? I don't get what you mean with that phrase..

check values in size, width and height columns in files table in the database.
