So title says it all, I was simply cleaning some unused files on my SSD bringing the size to 152 GB after the cleaning. I then use the laptop a bit before the laptop crashed likely due to one of my programs suddenly conflicting with each other, I restart the laptop and it runs perfectly fine, except for the fact that I suddenly lost 13 gb space and I am now at 139 GB space on my SSD with no real clue on how this happened any help on this matter will be appreciated.

One thing that might help, though I can't be too sure, is that the pagefile suddenly increased to 16gb usage despite me already having having 16 gb ram. I usually let windows handle the size allocation with the recommended size being 2.9gb and me suddenly losing 13 gb and suddenly having a 16gb pagefile seems dubious. I do not however remember what the pagefile size was prior to the crash, hope this helps!
