Edge de Crashing after having saved some PDF files

Hello, 

I have a problem with edge dev on my computer. 

When I open several PDF files (4 or 5) and if I want to save them in my computer, it works well until the second one and for the third, nothing happens. The browser is down, and I have to restart it...

This is very disturbing when you have to do successive research, there is a big waste of time.

Could you correct this behavior please, 

I will also send a message using the feedback tool in the browser.

Thanks.
