I have now re-read your post. As you commented out wire.h somewhere in your code that is the solution.!

It would have been handy to include some of the error messages to get a direction on your issue. I think you get messages that some variables/routines are double defined. If that is the case I suspect the reason is that in the file Adafruit_SSD1306.h, around line 41 it includes Wire.h.
Change in Adafruit_SSD1306.h the line from: #include <Wire.h> to something like : #include <scd30/SoftWire/SoftWire.h>

Thanks as I thought, it finds double definitions in both Wire and SoftWire. Make the change as I proposed. (I can't check as I do not have all your hardware and libraries installed)

I put the SoftWire folder from your library in Adafruit_SSD1306 library folder and added the line #include <SoftWire/SoftWire.h>

By any chance do you have any code snippet for integrating scd sensor with some other i2c device like bme sensor, oled etc?
That will work for me, I'll make the required changes.

The issue is still the same.. somewhere Wire.h is still included.. I see that in Adafruit_GrayOLED.h. You need to make the same change (around line 33). THis is part of the Arduino-GFX library.

There is no Adafruit_GrayOLED.h file in Arduino-GFX library folder. I also checked other files in the Arduino-GFX library, nowhere else is Wire.h included.

Weird.. I have just installed Arduino_GFX and the file shows up in mine.
Somewhere however Wire.h is still included. That is the root cause of the problem. Check all the code and includes.
An alternative to quickly check: Goto the ESP32 boards Wire library( I am on Ubuntu so it would be something like ~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/Wire/src). Rename Wire.h in this folder to Wire_org.h. Now try to compile (which should fail) and notice the path from which Wire.h is called.
Make sure to rename back after you have finished.
regards,
Paul

@paulvha I commented out the wire.h library from my code, and it worked. Is it a fine solution?
