Answer 1

I solved this issue by changing the Windows Terminal settings.json config file by adding the following:

1 - Find the settings on: Windows Terminal arrow down nearby the tab(s), Click to the settings button, and Click to Open JSON File field.

2 - Add this command to the config file like the example below:

"commandline": "\"C:\\Users\\Your Machine actual Username\\AppData\\Local\\Microsoft\\WindowsApps\\Microsoft.PowerShell_8wekyb3d8bbwe\\pwsh.exe\""

The original Windows Terminal config:

{
   ...
   "guid": "{574e775e-4f2a-5b96-ac1e-a2962a402336}",
   "hidden": false,
   "name": "PowerShell",
   "source": "Windows.Terminal.PowershellCore",
},
...

After Change:

{
   ...
   "guid": "{574e775e-4f2a-5b96-ac1e-a2962a402336}",
   "hidden": false,
   "name": "PowerShell",
   "source": "Windows.Terminal.PowershellCore",
   "commandline": "\"C:\\Users\\Your Machine actual Username\\AppData\\Local\\Microsoft\\WindowsApps\\Microsoft.PowerShell_8wekyb3d8bbwe\\pwsh.exe\"",
},
...

Don't forget to change You Machine Actual Username in the commandline field.
