What did you do? (required: The issue will be closed when not provided)

Clean install of both vim and vim-go on windows with a working install of go 1.13. Everytime I load a go file I get the above error. See below for details

What did you expect to happen?

The editor to open without en error message so that I can at least :GoInstallBinaries to finish the installation - this has not yet taken place, since executing any :Go... command gives a similar error

What happened instead?

The following error:
