Cant open maps

When i try open my maps, ue4 crashing. Please, help. Log

This happened after I made a simulation of the cloth through a new tool. I open the map for verification, it opened, the game started, after which the engine crashed. I tried to use the save from the “saved” folder, but it did not help, as well as the complete removal of the character on which the cloth simulation is used. Please, help. I’ve been doing this project for almost 1.5 years and, unfortunately, my last backup for the summer of 2017.
