Arduino compiling error

in Arduino & Crowduino

Greetings,

I recently purchased the Elecrow 5" HMI (DIS0750h) in hopes to build my own resource monitor screen for myself.

But I have watch several of the Tutorials and downloaded the lessons and the examples for this specific screen. But i have YET to get a single Arduino Sketch to properly compile.

I have tried reverting the LVGL to 8.3.11 from the newest 9.4.0, and it does change the errors but still no luck.
The errors seem to be declaration of function errors...

I have even TOTALLY uninstalled Arduino and reinstalled... including scrubbing all libraries. presently only running the libraries that are required, but still it won't compile. The latest attempt is with the "crowpanel-esp32-5.0" ino. and i get this error.
Compilation error: implicit declaration of function 'lv_mem_alloc'; did you mean 'lv_realloc'? [-Wimplicit-function-declaration]

Can anyone please help i feel like im running around in circles...
Thanks in advance..
Ettill
