What do you see when you compile, Post it using the code tags above </>
Quick check list:
Round Display by Seeed
Xiao ESP32C3 in the socket seat
BSP (Board support package) Espressif esp32 ver. 2.0.11 (3.0.5) is the current one.
TFT_eSPI graphics library, version 2.5.23 Installed from Wiki as TFT_eSPI_Master ?(just add it)
Lvgl if you use it, 8.3.7 all things equal.
NOTES edit the User_setup.h to the correct items (one display driver at a time ONLY, etc.)
for C3, S3 " #define GC9A01_DRIVER" is in the User_Setup.h…
User_setup_select.h Should be setup66 for seeed round display, BTW…
USE the User settings ino to test your settings.(edits)
load the demo and compile. should work from the get go.!

As an aside to the ROUND display.
So the Seeed Studio Round Display , albeit very nice looking is the Hardest of the seed products I would argue to get too work. Not because it’s not good hardware but the software is tricky. Once you get it going and gain the knowledge that it takes, it’s like a secret decoder ring for a lot of seeed MCU’s (BSP’s and LIB version) always has been but necessary to know as a new person trying to figure it out. (start with the RGB_Blinker.uf2 as a safety net , IMO) can be frustrating but rewarding all at the same time.
ASK FOR HELP!
best words I can offer.

Just to put a BOW on this , @Mark_Lucking did a master work article on Medium for the “round eye display” 
I suggest you read it to be re-inspired to take the technology on head long. Great Article!! and thanks for the props.
