platformio.ini is
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
Am unable to make any projects to work. My projects were working, then I switched to an ESP8266 which did not work, then switched back to an ESP32 and could not get any projects to work.
Any thoughts?

What is the code?
What is the output of a upload procedure?
How do you start the serial monitor?
Have you made sure to select the right project and environment using the "environment selection switcher?
Not enough info given 
#include <Arduino.h>
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
Serial.println("Hello");
}

I have tried several different “esp32” environments; but, no luck. All my programs for the esp32 were working Saturday. They were not working on Sunday.
What other information do you need?

And the project which you want to upload and that the above code resides in is called “test”? Regarding
It was all working Saturday, then stopped working on Sunday.
I am going to uninstall everything then reinstall it all back again.
If worse comes to worse, will install it on a different computer.
Thanks for your help.

Before you do that can you show a screenshot of VSCode?
Just press Alt+PrintScreen while VSCode is the active window, then Ctrl+V it into a new post.
Also you kinda didn’t answer my question? Creating a new project and not switching to it via the linked methoded might be the culprit.
I loaded PIO under “Atom” and it works perfectly.
So, the problem now is that no matter what I try to compile and run, it compiles and runs the first sketch.
Regarding your question, I didn’t understand it.
I run a project by clicking on the project in the window that shows all projects, the clicking on the source code. compiling and running it. Perhaps this is the wrong way to select a project to change, compile and run. How should I be selecting a project?
Thanks
George
Exactly that’s the issue.
PLEASE please, I’m trying to point you to the documentation since 3 posts, read it once: PlatformIO IDE for VSCode — PlatformIO latest documentation
Have you made sure to select the right project and environment using the "environment selection switcher?
Its all working…thanks for your help! Your “Arrow pointing to default” made it work!..
Duh!..not enough coffee here in my office!
I much appreciate your patience for a “newbee” to Platformio!
George
Yes, I have finally read the documentation! Again, I much, much appreciate your patience for a newbee who didn’t follow your instructions and didn’t read the documentation! I apologize for the incovenience and will try to do better in the future!
Many Thanks
George
