After I click on "CHOOSE A FILE TO START", the window below will pop as usual and I just need to choose the file to go to the next steep that is choose the signer/add fields/choose folder to keep the file.... But after I Choose the File and Confirm, this window closes and nothing else happen!! this start to happen in the last tree days.
Just to help understand, this above is the last window we can see. Once we confirm "Choose", this windows closes and nothing happen.
