Description

I have a point layer with 2,365,043 features that I am trying to run the Snap geometries to layer algorithm on. Every time I run it QGIS crashes. I understand this is a very large file to work on but it should not crash QGIS.

The input and reference layer are the same and I am using a tolerance of 1 meter with the Prefer aligning nodes, don't insert new vertices option.

I have attached a Project file and here is a Dropbox link to the data - https://www.dropbox.com/sh/f7jeawyjgszwttu/AAAHnguxoB1XORHsB5J5_tKHa?dl=0

Crash ID: 635c0b4de2060f48928b3f2f254160d072d28d58
