Command failed: install-tool golang 1.20.0

[omercnet]

Recently I (sometimes) get this artifact error

I'm having a hard time understanding or reproducing this - any idea what might cause it?
The biggest conundrum is that my go.mod specifies go.19 so I'm not sure why it's even trying to install 1.20
