Bug? File load error

Hi. I have a strange problem, a class problem (IClassFactory). When I want load a file in the file manager, B4A throw the following error: -Attached Files-

I use w7, 64 bits. I tried reinstall B4A but nothing changed: I still have the same problem. Any idea? Thanks.

Strange error. Can you enable the IDE logs and post them: https://www.b4x.com/android/forum/posts/50478/ ?

What happens if you click on the sync button? Or drag and drop a file?
