Upgrade from OJS 2.4.8 to 3.X.X return error 500 after a while

Hello I’m trying to upgrade my OJS 2.4.8 to 3.x.x. I’m doing it on my localhost. And everything starts fine, then in some minutes a error 500 returns, in Xampp log nothing is returning on access_log or error_log.

Can anyone help me with this problem?
