VScode integrated terminal suddenly throws an error during initialization - bash

Question

I'm using the most recent VScode on Ubuntu 22.10 and experiencing the following issues while opening ZSH and BASH shells in the integrated terminal. The standard Ubuntu terminal works without errors.
After starting a ZSH integrated terminal:
compdump:138: command not found: mv
/home/user/.oh-my-zsh/oh-my-zsh.sh:56: command not found: mkdir
/home/user/.oh-my-zsh/tools/check_for_upgrade.sh:29: command not found: git
/home/user/.oh-my-zsh/oh-my-zsh.sh:115: command not found: rm
getent:6: command not found: grep
_p9k_init_cacheable:59: command not found: uname
_p9k_init_cacheable:61: command not found: uname
BASH
Command 'uname' is available in the following places
* /bin/uname
* /usr/bin/uname
The command could not be located because '/bin:/usr/bin' is not included in the PATH environment variable.
uname: command not found
Just several hours before, it worked just fine. Then I tried to set up Remote SSH to another Linux machine (Fedora 36, with the same sort of errors I was also unable to resolve by googling).
Using the #modified keyword in Settings, I ensured that no unexpected changes had been made. The PATH is the same as in the fully operational standard terminal.
Wondering what could be the issue.
UPDATES.
PATH variable:
/usr/local/cuda-11.7/bin:/home/user/.conda/envs/env/bin:$PATH
The problem.
Unlike the complete PATH expansion in the standard terminal, PATH was expanded partially (omitting /usr/bin, etc.) in the integrated terminal.

Answer 1

Based on this error,
The command could not be located because '/bin:/usr/bin' is not included in the PATH environment variable.
I suggest you run,
export PATH="/usr/bin:$PATH"
To add /bin:/usr/bin to your PATH
Having :$PATH in your PATH means that the sheell will add the variable $PATH to the end of your PATH

Answer 2

The cause of the issue the following configuration from the User settings:
terminal.integrated.env.linux": {
"PYTHONPATH": "/media/user:/media/user/common:$PYTHONPATH",
"PATH": "/media/user:/media/user/common:$PATH"
}
While the PYTHONPATH variable is expanded properly in the integrated terminal, the PATH is expanded partially to something shown in the UPDATES section of the question. To build on top of the answer by #Orion447, looking for any potential place where PATH could get corrupted is the approach that likely solves the problem.
