I had a similar issue with an ideaspark® ESP32 Development Board 16MB Integrated 1.9 inch ST7789 170x320 TFT.

In my case, I needed to set TFT_RST to 4 instead of -1, otherwise the screen was blank like in your case.

HTH!

At the moment the TFT_eSPI library has no built is support the c5 variant and I don't have a c5 to adapt and test it.
