PlatformIO Core not updating to the latest version on macOS 11.6.x

I’m unable to update PlatformIO Core to the latest version on macOS 11.6.1 (Bug Sur).
It currently is at Core 5.2.0 and Home 3.3.4.

The PlatformIO Core & Home updates work fine for macOS 10.15.7 (Catalina) and macOS 10.14.6 (Mojave) at Core 5.2.3 & Home 3.4.0.

I get the following message when attempting PlatformIO Core upgrade from Core 5.2.0 & Home 3.3.4 on macOS Big Sur:

$ platformio upgrade
Please wait while upgrading PlatformIO ...
PlatformIO has been successfully upgraded to 5.2.0

Any assistance would be greatly appreciated. Thank you.

Any feedback on above?


What happens when you do pio upgrade --dev?

Please remove ~/.platformio/penv & ~/.platformio/python3 folders. Restart VSCode.

Below is the message I got after pio upgrade --dev.

After removing the ~/.platformio/penv & ~/.platformio/python3 folders, and followed by a VSCode restart resolved the issue.

Thank you Ivan & Max.
