How do I fix this window
 

Spent the weekend insulating windows with expanding foam. Did 13windows with
no problem with help. On one window we used the wrong type of foam(fast
expanding) and the window is now stuck almost closed. I ran a couple of
passes with a reciprocating saw down each side of the window thiking the
kerfs might give it enough room to move back into place but this did not
help. This is suppose to be a swing out window but it will not even do that
anymore. Help. Window is in our bedroom and we will be sleeping tonight with
towels stuffed in the crack.
