ESP32-3248S035 LVGL_arduino example showing black screen

Description

I successfully uploaded the lvgl_arduino example using Arduino IDE to my LCD Screen (ESP32-3248S035), however it now only shows a completely black screen.Yes, I’m sure my LCD is working fine, as before it was successfully uploaded, it showed the default widget. Please help as this is my first time working with LVGL, and I am a bit overwhelmed.

What do you want to achieve?

I want to try using the various lvgl examples, but can’t seem to make them work.

What have you tried so far?

I downloaded the LVGL_Master from this site, so Yes it should be updated to the latest version. I copied the lvgl_config template to the arduino library.
