I can reproduce it when I try to execute It happens when trying to call shell-builtins from/in PS1:

Working: PS1="\$(date '+%s: ')$PS1"

root@hostname:~# PS1="\$(date '+%s: ')$PS1"
1573146144: root@GARDENA-163008:~#

Hanging: PS1="\$(echo 'MyPrefix ')$PS1"

root@hostname:~# PS1="\$(echo 'MyPrefix ')$PS1"

It seems that this issue has been resolved by commit 943e81f5db56eedbadf43459afbc967d100f9da2 [1] which is part of the 1.31.1 release.
