you should be able to run cmd command in PowerShell, is there an error?
you can also run sfc withing powershell just like in CMD.

cmd runs in powershell
I wont run SFC yet as it is at 75% of the feature update

I am doing a SFC now.
CMD will still not run unless run in PS.
Why is that? Is that normal behavior now?

Could also be option #3 or option #7 in this guide:
Command Prompt not working or opening in Windows 11/10

SFC fixed things, cmd still wont open on its own without PS
Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files and successfully repaired them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.

Also try
dism /online /cleanup-image /restorehealth

If all else fails, try to repair Windows by doing an in-place upgrade:
Repair Install Windows 10 with an In-place Upgrade

Did you reboot after the fix?

@sdowney717
run gpedit.msc as Admin and head to:
User Configuration/Administrative Templates/System

on the right make sure that "Prevent access to the command prompt" is set to "Not Configured"
then run gpupdate.exe in PS if you changed the setting.

Just checked and it is set to not configured

Can you open the cmd.exe from C:\Windows\System32 folder

Nope. Click on it, and mouse turns into blue circle for about 20 seconds, then nothing.
Takes a LONG time to open properties, but run permissions on the file look normal

just did the restore health, rebooted, cmd still will not run by itself.
I might do the inplace repair, so far things are working ok otherwise.

You know when I click cmd,exe in file manager, it takes a long time to think about whatever it is doing and fails to do anything.
But when I startup chrome browser in about 2 seconds it is up and running.

In PS, type cmd and it is instantly running cmd in ps
