File Manager doesnt open when clicked in Mendix Studio Pro 8

I created a new Mx 8 project, but the “Browse...” function of the File manager doesn’t seem to work. Turn-off all security to see if this isn't the problem, but no result. Mendix Console & Chrome Console both doesn't display any errors. Anybody having the same issue or knows a fix for this?

Probably a bug, i encounter the same problem, security and inherited access rules are set accordingly.

A workaround for a JSON file/other (small) files was;

1) decode your file to base64

2) create a variable with that decoded base64

3) generate a file by using  base64tofile
