'&' will cause an error when using got or goT on Windows Powershell

vim-gtfo/autoload/gtfo/open.vim

Line 159 in ec93bd3

let cdcmd = (''==#drive?'':drive.' & ').'cd '.shellescape(l:dir, 1)

'&' can be used in cmd, but is reserved in powershell and will cause an error when used in powershell. The '-and' connection command should be used in powershell.

When changing '&' to '-and', got and goT work fine

Are you setting g:gtfo#terminals ? Please mention that.

What is the full value of your 'shell' and $COMSPEC?

:put =&shell
:put =$COMSPEC

I assume you are hitting this line:

vim-gtfo/autoload/gtfo/open.vim

Line 168 in ec93bd3

silent exe '!start '.s:termpath.' "'.cdcmd.'"'

for which s:force_cmdexe() does not apply.

The vimrc for gtfo:
" for gtfo
let g:gtfo#terminals = { 'win': 'powershell -NoLogo -NoExit -Command'}

Add debug echom to open.vim:
161:echom "shell:" . &shell
162:echom "COMSPEC:" . $COMSPEC
163:echom "cdcmd:" . cdcmd

The debug output:
shell:C:\Windows\system32\cmd.exe
COMSPEC:C:\Windows\system32\cmd.exe
cdcmd:C: & cd "C:\Users\luominghao\vimfiles\plugged\vim-gtfo\autoload\gtfo"
