I’m thinking something didn’t work in the upgrade. Mine, of course, worked.
Is anything listed under Help->Toggle Developer Tools, on the Console tab?
This thread shows a similar problem on a Mac, which was caused by Microsoft’s C++ extension, which PlatformIO depends upon. PlatformIO Toolbar and Home icon not showing in VSCode - #3 by daaron
I would also check that you have enough free disc space on your drive where VSCode is installed, and on your C drive where My Documents lives. Just in case.
Cheers,
