When launching a subshell in a unix-like shell (in my case, MSYS2 BASH in such a way, that $SHLVL is incremented),
the shell gives an error like:
bash: command: __vsc_prompt_cmd_original not found
Updated to the altest version and turned off all extensions to test too.

Steps to Reproduce:

1. Launch an instance of a unix shell that uses an rc file to load configs (Create New Terminal With Profile)
2. Launch another instance inside of the previous shell (in a way that $SHLVL is incremented)
3. There will be an error message like command: __vsc_prompt_cmd_original not found

Thanks in advance
