The current Release of MCUFRIEND_kbv does not work properly with OPENSMART HX8352B
The Beta on GitHub does work. I intend to issue a new Release soon.
I have not any intention of supporting OPENSMART boards on a ESP32.
If you want speed with OPENSMART, buy a Uno.
I strongly suggest that you remove the OPENSMART_TFT folder. It contains a hacked copy of an obsolete MCUFRIEND_kbv library. I would not mind if they had chosen a different class name. Arduino will be confused if you have two different versions of MCUFRIEND_kbv
