flutterin the command prompt and in PowerShell.
Actual results
Trying to run flutter from a freshly downloaded .zip of Flutter 3.32.7 on Windows 10 fails when the PowerShell language mode is ConstrainedLanguage:
PS C:\src> flutter
New-Object: C:\src\sdks\flutter\bin\internal\update_engine_version.ps1:72
Line |
72 | $utf8NoBom = New-Object System.Text.UTF8Encoding($false)
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| Cannot create type. Only core types are supported in this language mode.
Error: Unable to determine engine version...
Running flutter from the command prompt shows the same error but also immediately closes the command prompt window, making it very hard see what went wrong.
