Please help me to deal with PowerShell environment variable.

I had learned that PowerShell has special syntax to access the system environment variable values. So I've tried to execute:

```
$env:Temp

```

in the PowerShell 6.2.4 console on Windows 10. The output is strange:

```
C:\Users\OD42B~1.BOR\AppData\Local\Temp

```

It has my Windows user name shortened to the 8.3 form.
The problem is that I can't use the `cd $env:temp` command, it displays the following error:

```
cd : An object at the specified path C:\Users\OD42B~1.BOR does not exist.

```

But I can do `cd %temp%` in the `cmd` terminal.

I've tried Windows PowerShell app (`%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe`) but `cd $env:Temp` does not works either.

I've checked environment variable configuration option (Sytem properties\Environment variables) and both `TEMP` and `TMP` variables are shown using the long form profile folder name, like `c:\users\o.borolongprofilename\AppData\Local\Temp`.

How can I make `cd $env:Temp` work for a non-8.3 profile name in the PowerShell?

### UPD

* PowerShell `get-childitem env:Temp` output is `C:\Users\OD42B~1.BOR\AppData\Local\Temp`.
* Cmd `echo %temp%` output is the same `C:\Users\OD42B~1.BOR\AppData\Local\Temp` (but `cd %temp%` works in the cmd).
* `TEMP` environment variable in the UI is set properly (value shown is like `c:\users\o.borolongprofilename\AppData\Local\Temp`).

However `TEMP` value is shown like `%USERPROFILE%\AppData\Local\Temp` when I try to edit `TEMP` using the UI.
* PowerShell `get-childitem env:userprofile` displays full name like `c:\users\o.borolongprofilename` (surprise).

### UPD2

I've just checked PowerShell 7 rc2 but the result is the same: `cd $env:Temp` does not work.

### UPD3

Thank you for helping me.
