When you use this command after installing the app- httpx -h
Sometimes this type of error occurs {-Error: Option '-h' requires 2 arguments.}
If you are encountering this error at the moment, please update your Kali system first, then perform an upgrade. Afterward, restart your Kali system, and this error should no longer occur.

I had a similar issue.
It turned out that the package manager (apt) installed the python3-httpx on the system. So when you run httpx -h, the command that is being executed is not related to the ProjectDiscovery's httpx.
You should uninstall and purge data, which is related to apt python3-httpx, and clear cache.
Reinstall projectdiscovery httpx, and check if you have the latest version of Go (if you install it with Go).

you are right.
which httpx returned /usr/bin/httpx. I deleted the it using sudo rm /usr/bin/httpx.
now which httpx will return the correct httpx, something like this - /home/username/go/bin/httpx
