On your own machine, print your PATH and read it as the ordered list it is. Use which on node, python3, git and any tool you rely on, and note which directory each comes from.

Finally, find a process with ps aux piped through grep, and stop something harmless you started yourself. These are the skills that turn the terminal from a place you visit into a place you work.
