UE5.3.2 fatal error

Hi everyone, I’m new to this software and community.
I’ve been developing a project on my own. The problem is that every time I close the level I’ve created, it crashes. I noticed this when I imported Blender assets into the level.
If anyone could point me in the right direction to solve this problem I would be very grateful.
Thank you!
This is the fatal error that appears every time I close the program or try to change levels:
