Hi,
Please clear your cache and try to work on customizer and let me know.

Please share the Black Screen shot where you stuck or getting an error or something.

also
Please check these php variables and try to make them have these values:
memory_limit = 256M
upload_max_size = 64M
post_max_size = 64M
upload_max_filesize = 64M
max_execution_time = 300
max_input_time = 1000

when you do to customizer then you should disable preloader due to that you see the black screen.
For editing your content you dont need customizer you should use edit page with elementor.
I have disable the preloader for now. you can enable it from customizer
general -> site options at the bottom second last option preloader effect enable or disable it.

Hi,
For Lana Slider:
Login to wp-admin > Go To page where Lana Slider Added > See on Top Bar > Editor with Elementor > You will see option on Left Side.

Thanks,

Ok – Great.
