Unable to compile for Uno after reinstall

Hi, I created a blank uno project, just the startup and loop in there and it fails compilation

The terminal process "C:\Users\spenc\.platformio\penv\Scripts\pio.exe 'run'" terminated with exit code: 1.

Seems like the compiler is really, really broken.

Please open a Windows Explorer and go to C:\Users\<user>\.platformio\packages\ and remove the folders toolchain-atmelavr and framework-arduino-avr. Also remove the folder C:\Users\<user>\.platformio\.cache\ if it exists. Then build the project again. PlatformIO should now redownload fresh copies of everything.

Just as a heads up, that almost worked, ended up having to erase everything manually, uninstall vscode and re-install it, weird eh… ho hum that’s computers for ya.

Cheers for the assist
