I have this web radio working sketch that I want add to it a function to retrieve weather temperature from OpenWeatherMap.
Independently both sketches are working.
When I add to the web radio sketch #include <HTTPClient.h>
#include <ArduinoJson.h> I get compile error
Compilation error: Audio.h: No such file or directory
here is the web radio working sketch:

Is that code working? It already includes #include <HTTPClient.h> and #include <ArduinoJson.h>
Doesn't this contradict the following statement?
How about an otherwise-empty sketch, but with the #include statements? This worked for me
#include <Wire.h>
#include <HTTPClient.h>
#include <ArduinoJson.h>
#include <Audio.h>
void setup() {}
void loop() {}
Make a copy of what you have, with just the twenty #include, and empty setup and loop
If that works, start putting code back.
(BTW, you don't need <Arduino.h> in an .ino -- it's "silently" tacked on at the top automatically when compiling. Also, you have <AudioAnalyzer.h> twice.)
Without [quote="embeddedkiddie, post:3, topic:1447027"]
#include <HTTPClient.h> and #include <ArduinoJson.h>
[/quote]
it is working.
@kenb4
Your suggestion worked, no more compile errors.
Just that now, after adding all the code and uploading the display shows nothing and the serial monitor gives the following message:

This message is most likely to appear when the ESP32S3 starts up or resets. If the message appears repeatedly, there may be an error causing the reset.
How about breaking down the sketch into smaller sections and testing them step by step?
At the very least, it's better to add functionality step by step, ensuring you create a working sketch, rather than trying to code everything at once.
Sorry but since I don't have the same board or components as you have, it's difficult for me to debug the code in post #2, for example, in my head.
I have one thought.
Web radio programs likely run on core 0, to get mp3 streaming data over the internet.
I'm not sure if it's possible to access OpenWeatherMap on core 1 at the same time.
I'd like to hear the opinion of someone with expertise.
Unless you go out of your way to spool up FreeRTOS tasks on Core 0, most "Arduino-Like" code runs on Core 1. The ESP32 audio library handling the web radio may indeed do this and run tasks on Core 0. Arduino setup() and loop() functions run in a Core 1 task spooled up by main.cpp. All functions called by those two function would also be running on Core 1 (again, unless they launch tasks on Core 0). Does OpenWeatherMap run on other processors besides ESP32? If so, I'd guess it doesn't have ESP32-specific code to run on Core 0. Thus, in all likelihood, it's running on Core 1 already.
It works now, I had to change USB CDC on Boot to disabled.

Thank you everybody!!!
@kenb4
Can you, please, explain why working with new empty sketch, adding all the include first, worked?
It may not be that specifically. First, do you have the old sketch saved, and it still fails?
If so, in the Preferences/Settings, turn on Show verbose output during compile. Then create a new sketch, copy&paste over the .ino into the new one, and build it.
If at least one fails, right-click on the Output and Copy All. Paste it here as <CODE/>. If one works, paste that too separately so we all can look for differences.
If the broken build is "no longer reproducible", then it might be some glitch in the temporary build files.
Just presenting the facts.
On the original web radio sketch I had on top a comment about the required version of the ESP32-AudioI2S. When you advice to start fresh with just adding only the #includes I did not copy the comment. I followed your advices adding only the #includes, no error, after I added the the rest of the web radio sketch (tested, working), followed by the weather sketch part. All working. Later, I added the comment and the error came back, I removed the comment and all working.
Here is the comment:
//ESP32 Internet Radio
//Important Note: The following sketches require version 3.4.1 of the library ESP32-audioI2S.
//Please select version 3.4.1 in the library manager.
