I was just wondering if insulation foam (I used regular Great Stuff from HD) can expand in dry conditions around a window (frame) and cause warping and damage to the window up to and including breakage.
Can insulation foam expand around window framing and cause warping

I have personally seen it bow "trimmer" studs in a framed window opening. It could easily warp, bow, or move a window frame itself. Breakage would likely be caused by users messing with/forcing the out of plumb/square/true window?
Note: you can buy "low expansion" foam specifically designed to avoid this issue.
