Hey Miguel,
No worries about the response time. I am going to need to you reproduce this in an empty, new, blank project so I can verify this bug occurs without any outside influence from other assets.
Before doing this, I would uninstall your current version of 4.8, and do a clean re-install with 4.8.1. to verify this crash is valid and still occurs. If you still do get the crash, please provide me with your crash log as a .txt file zipped into a folder and attached here.
Thank you,
