RC17 Closing when opening folders that had a downloaded webpage

This is happening on two projects. RC17, on Windows 10.

Problems that I’m facing:
[] When I tried to open a folder that had a downloaded webpage, Scrivener closed without asking me.
] I can add a new webpage to a folder that does not contain one
[*] But if I do the above, then I can no longer access that folder.

I had very important information there, and can’t access it.
