I use Espressif-IDE.

I have an issue with a few of my older projects.
I had been using a different ESP-IDF version.

They compile fine, but when I want to flash/launch, I get the following error:
If refers to an idf5.0_py3.9_env.
However, I am using IDF 5.1

Funny enough, when build the project, if finds the 5.1 version fine: I have been through the whole project folder, grepping for the '5.0_py3.9' string, but find NO references anywhere.
Also tried to go through the .espressif folder to see if there was any references to my project that way. No luck.
Where the heck is this stored?

How can I 'reset' this launch to use the correct version of my python environment?

Here is something similar: https://esp32.com/viewtopic.php?t=20585

Thank you, but not the same.
This is clearly related to Espressif-IDE (or Eclipse, actually), as the program compiles and launches fine in a command line ESP-IDF environment.
The silly idf5.0_py3.9 env is only used when launching in Eclipse. Building works fine.
And I just cannot find WHERE it is stored.
