just wanted to ask a question if anyone has any experience or knows of this problem.
So I'm getting more and more into printing and I have very recently had an issue where the layers of the print are very easily separating and the infill material crushes under minimal pressure I have one that almost completed then failed I knocked it over and then the issue started, I have replaced the nozzle since then and no difference as well as fiddling with settings in Cura if anyone knows anything plz send help

In the picture, the above one is the after and below is before.
