VS Code Platform Initialization error

PlatformIO IDE
1

My VS Code PlatformIO opens existing BluesWireless Swan R5 device based project fine and creates new projects for this device (Arduino Framework). However, I get “Could not initialize projects” error when using the Project Wizard to create new project for either Blues Swan R5, or Blues Cygnet. > Could not initialize project

PIO Core Call Error: “The following files/directories have been created in C:\Users\jmeck\OneDrive\Documents\PlatformIO\Projects\Cygnet TEST\r\ninclude - Put project header files here\r\nlib - Put project specific (private) libraries here\r\nsrc - Put project source files here\r\nplatformio.ini - Project Configuration File\r\nResolving blues_cygnet dependencies…\r\n\n\nUnknownBoard: Unknown board ID ‘blues_cygnet’”

This should not happen, they are included in the latest ststm32 platform.

Does the platformio.ini of those projects explicitly pin the version of ststm32 to make sure it gets pulled from the offical version and not some other source that happens to be installed?

platform = ststm32@19.3.0

@maxgerhardt Thanks for the response and suggestion. As the Wizard fails to start, no plaformio.ini file is created. However, thanks to another forum suggestion, I found the fix to be deleting a specific folder in the .platformio folder at users home directory.
