Powershell Invoke-Item no longer works to open directories in Explorer

I frequently use

ii .

in PowerShell to open the current directory in Windows Explorer. This used to work all the time, but now nothing happens.

The Invoke-Item cmdlet still works. Doing ii somefile.txt opens that file in a text editor. But directories don't work anymore.

In addition start . doesn't work. Using explorer . does work.

Running

Trace-Command -Name ParameterBinding {ii .} -PSHost

returns

DEBUG: ParameterBinding Information: 0 : BIND NAMED cmd line args [Invoke-Item]
DEBUG: ParameterBinding Information: 0 : BIND POSITIONAL cmd line args [Invoke-Item]

DEBUG: ParameterBinding Information: 0 : CALLING EndProcessing

Running

Trace-Command -Name CommandDiscovery {ii .} -PSHost

returns

DEBUG: CommandDiscovery Information: 0 : Looking up command: ii
DEBUG: CommandDiscovery Information: 0 : Alias found: ii  Invoke-Item
DEBUG: CommandDiscovery Information: 0 : Cmdlet found: Invoke-Item  Microsoft.PowerShell.Commands.InvokeItemCommand,
Microsoft.PowerShell.Commands.Management, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

I guess maybe there's a file association problem or something. But I can't figure out what Invoke-Item is actually calling or how to change it.

How can I get this working again?

It is very tough to figure out exactly why it might not work for you anymore, but why not use the alternative which is the same in powershell and cmd:

start .

( explorer . works too)

If ii . is important, then try restarting Powershell console and / or the computer. Also try doing ii . -whatif to see if you get any clue on why it doesn't work anymore.
