Project suddenly will not launch 4.18

Hello, I’m suddenly having an issue not opening a project for a class. It’s very vital and this has only just started happening. I needed to restart my computer, and now I can’t open my file. I desperately need this file due to the fact that this assignment is due tonight! I appreciate any help.

This is the error report below

I’ve managed to get the project to at least open by removing the Saved and Config folders, and it seems to be an issue with my current particle emitter. I can create a new particle emitter and it works just fine. However I can’t touch or delete my original particle emitter without the program crashing entirely
