Hi MawiRecon, how do you add TFT_eSPI lib to your PIO project, can you take a screenshot of the workspace of your project PIO? The following screenshot is my PIO's workspace. You can see the location of the User_Setup.h file.

I'll preface this by saying that I'm new to PlatformIO/VS. I've been an Arduino IDE user for a while and completely comfortable in that IDE.
1. A description of the problem and the conditions that cause it to occur
I'm trying to run a simple "Hello Word" print test on my TFT display in effort to get familiar with PlatformIO.
The program compiles and uploads successfully, however the TFT remains blank.
The issue is no doubt user error for updating User_Setup.h, however I can't figure out what the error is.
I've successfully tested this in Arduino IDE just to make sure the components are functioning properly.
I've added the TFT_eSPI lib to my project and started updating the User_Setup.h to align with my TFT and controller. Below are the relevant definitions, with everything else commented out. The pinouts are correct as this works using ArduinoIDE.
main.cpp is a simple "Hello World" print test:
I've tried some of the example programs as well, still with no luck. Just a blank screen.
2. IDE (e.g. Arduino or PlatformIO)
PlatformIO
3. TFT_eSPI library version
2.5.43
4. Board package version
