using async times out - git info not shown

[olifluous]

OS version: pop os 22.04
Kernel version: 6.0.6-76060006-generic
font: Space Mono Nerd Fonts

when configuring my .zshrc file with async for vcs_branch, vcs_status and vcs_dirty, my prompt no longer displays git info.

~/.config/zsh/themes/alien/libs/zsh-async
❱ ./test.zsh -v -x
sigwinch_test.txt

my .zshrc config
.zshrc
and for completeness, my .zshenv file

when removing the :async from the file, git info is displayed again

Have i a setting wrong, am i missing a prerequisite? Any help would be appreciated

Issue is no longer present. I don't know what resolved it.
