如 this thread 中所述，问题可以通过

解决

This issue was fixed in 2.2.0-beta3 version of PSReadLine. You can fix this by upgrading to the latest 2.2.0-beta4 version of PSReadLine. Instructions for doing so:

1: stop all instances of pwsh.

2: from cmd.exe run:
pwsh -noprofile -command "Install-Module PSReadLine -AllowPrerelease -Force"

此外，如果您想卸载以前的安装程序，请按照以下步骤操作

If you want to remove that beta version of PSReadLine and use the 2.1.0 version of PSReadLine that's shipped with PowerShell 7.2, you can:

1: run pwsh -noprofile -noninteractive to start pwsh without loading PSReadLine

2: run Uninstall-Module -Name PSReadLine -RequiredVersion <2.2.0-beta1 or 2.2.0-beta2> -AllowPrerelease to remove the module. Or, you can manually remove that module folder.
