phpstorm encountered a problem when looking at the value of a variable when using xdebug for breakpoint debugging .

the array variables above cannot view the content, but only show can not get property
what caused this?
add:
suspected to be a problem at the var_dump level. I added the following code to the php.ini file, but the problem was not solved

;var_dump
xdebug.var_display_max_children=128
xdebug.var_display_max_data=512
xdebug.var_display_max_depth=5
