There's no line 358 in application/Espo/Core/Application.php in v7.0. Nor in 6.0.

I know that I check the file, But this is the error message in the errors log.
the portal was working, I don't know what happened

Perhaps have a look at line 352 of the file itself? What code is there? Compare it to the original file.
